Internet censorship is control or suppression of the publishing or accessing of information on the Internet. The legal issues are similar to offline censorship.
One difference is that national borders are more permeable online: residents of a country that bans certain information can find it on websites hosted outside the country. A government can try to prevent its citizens from viewing these even if it has no control over the websites themselves.
Filtering can be based on a blacklist or be dynamic. In the case of a blacklist, that list is usually not published. The list may be produced manually or automatically.
Barring total control on Internet-connected computers, such as in North Korea, total censorship of information on the Internet is very difficult (or impossible) to achieve due to the underlying distributed technology of the Internet. Pseudonymity and data havens (such as Freenet) allow unconditional free speech, as the technology guarantees that material cannot be removed and the author of any information is impossible to link to a physical identity or organization.
In November 2007, "Father of the Internet" Vint Cerf stated that he sees Government-led control of the Internet failing due to private ownership.
Software
Jo Glanville, editor of Index on Censorship observes that "censorship, for the first time in its history, is now a commercial enterprise".[1]
Technical censorship
Some commonly used methods for censoring content are:[2]
- IP blocking. Access to a certain IP address is denied. If the target Web site is hosted in a shared hosting server, all websites on the same server will be blocked. This affects IP-based protocols such as HTTP, FTP and POP. A typical circumvention method is to find proxies that have access to the target websites, but proxies may be jammed or blocked, and some Web sites, such as Wikipedia (when editing), also block proxies. Some large websites like Google have allocated additional IP addresses to circumvent the block, but later the block was extended to cover the new IPs.
- DNS filtering and redirection. Don't resolve domain names, or return incorrect IP addresses. This affects all IP-based protocols such as HTTP, FTP and POP. A typical circumvention method is to find a domain name server that resolves domain names correctly, but domain name servers are subject to blockage as well, especially IP blocking. Another workaround is to bypass DNS if the IP address is obtainable from other sources and is not blocked. Examples are modifying the Hosts file or typing the IP address instead of the domain name in a Web browser.
- Uniform Resource Locator (URL) filtering. Scan the requested URL string for target keywords regardless of the domain name specified in the URL. This affects the HTTP protocol. Typical circumvention methods are to use escaped characters in the URL, or to use encrypted protocols such as VPN and TLS/SSL.[3]
- Packet filtering. Terminate TCP packet transmissions when a certain number of controversial keywords are detected. This affects all TCP-based protocols such as HTTP, FTP and POP, but Search engine results pages are more likely to be censored. Typical circumvention methods are to use encrypted connections - such as VPN and TLS/SSL - to escape the HTML content, or by reducing the TCP/IP stack's MTU/MSS to reduce the amount of text contained in a given packet.
- Connection reset. If a previous TCP connection is blocked by the filter, future connection attempts from both sides will also be blocked for up to 30 minutes. Depending on the location of the block, other users or websites may also be blocked if the communication is routed to the location of the block. A circumvention method is to ignore the reset packet sent by the firewall.[4]
- Web feed blocking. Increasingly, incoming URLs starting with the words "rss", "feed", or "blog" are blocked.[5]
- Reverse surveillance. Computers accessing certain websites including Google are automatically exposed to reverse scanning from the ISP in an apparent attempt to extract further information from the "offending" system.[citation needed]
One of the most popular filtering software programmes is SmartFilter, owned by Secure Computing in California, which has recently been bought by McAfee. SmartFilter has been used by Tunisia, Saudi Arabia and Sudan, as well as in the US and the UK.[1]
"By-catch"
Automatic censorship sometimes stops matter which it was not intended to stop. Examples are:
- Automatic censorship against sexual words in matter for children, set to block the word "cunt", has been known to block the Lincolnshire (UK) placename Scunthorpe. Likewise, a block against the word "penis" may block the Yorkshire (UK) placename Penistone; and at least one big web forum, set to block "twat", automatically changes "wristwatch" into "wris****ch", and refuses the name "Dick" even when it clearly means a man's name. Other examples are blocking "specialist" because it contains the drug name "cialis", and changing "Essex" to "Es***".
- Within Wikipedia, a block against the word "admin" in usernames of users who are not administrators, has been known to query usernames containing the placename and game-name Badminton.
- The Yahoo email group system's profanity blocker, set to block the abbreviation "CP" in descriptions of email groups, treating it as meaning "child pornography", blocked it when a journalist setting up an email group used "CP" to mean "Canadian Press". Likewise, it blocks the word "pornography" - including in the sentence "No hard or soft pornography will be allowed".
- Aspies for Freedom blocks the word "retarded", and replaces it with "***" even when not referring to a "autistic" person.
Circumvention
There are a number of resources that allow users to bypass the technical aspects of Internet censorship. Each solution has differing ease of use, speed, and security from other options.
Proxy websites
Proxy websites are often the simplest and fastest way to access banned websites in censored nations. Such websites work by being themselves un-banned but capable of displaying banned material within them. This is usually accomplished by entering a URL address which the proxy website will fetch and display. They recommend using the https protocol since it is encrypted and harder to block.
Java Anon Proxy
Java Anon Proxy is primarily a strong, free and open source anonymizer software available for all operating systems. As of 2004[update], it also includes a blocking resistance functionality that allows users to circumvent the blocking of the underlying anonymity service AN.ON by accessing it via other users of the software (forwarding client).[citation needed]
The addresses of JAP users that provide a forwarding server can be retrieved by getting contact to AN.ON's InfoService network, either automatically or, if this network is blocked, too, by writing an e-mail to one of these InfoServices. The JAP software automatically decrypts the answer after the user completes a CAPTCHA. The developers are currently[citation needed] planning to integrate additional and even stronger blocking resistance functions.
Virtual Private Networks (VPNs)
Using Virtual Private Networks, a user who experiences internet censorship can create a secure connection to a more permissive country, and browse the internet as if they were situated in that country. Some services are offered for a monthly fee, others are ad-supported.
Psiphon
Psiphon software allows users in nations with censored Internet such as China to access banned websites like Wikipedia. The service requires that the software be installed on a computer with uncensored access to the Internet so that the computer can act as a proxy for users in censored environments.[6]
Tor
Tor is a free software implementation that allows users to bypass Internet censorship while granting strong anonymity; see Tor (anonymity network)#Weaknesses for its weaknesses.
Sneakernets
Sneakernet is a term used to describe the transfer of electronic information, especially computer files, by physically carrying data on storage media from one place to another. A sneakernet can move data regardless of network restrictions simply by not using the network at all.[7]
The volunteer organization Information Without Borders is attempting to implement a sneakernet routing protocol for providing cheap Internet access to developing and post-conflict regions using donated flash drives, PDAs and mobile phones. The protocol is also useful for providing free and open Internet access to people living under repressive regimes that restrict free expression by limiting access.[8] This protocol is still under development, but actual flash-drive sneakernets are known to exist in Cuba. Flash-drive sneakernets were used in 2008 to distribute a video of a student asking why Cubans are not permitted to access web sites like Yahoo.[9]
Around the world
The following sections follow the OpenNet Initiative (ONI) categorization scheme: Pervasive, Substantial, Nominal, Indirect, Watchlist.[10]
In 2006, Reporters without Borders (Reporters sans frontières, RSF, a Paris-based international non-governmental organization that advocates freedom of the press) published a list of the 13 "enemies of the Internet":[11] The organization classifies a country as an enemy of the internet because “all of these countries mark themselves out not just for their capacity to censor news and information online but also for their almost systematic repression of Internet users.” [12] The list is updated annually and now includes 12 countries in 2009:
Pervasive
While there is no universally agreed upon definition of what constitutes "pervasive censorship", RSF (Reporters sans frontières) maintains an internet enemy list[11] while the OpenNet Initiative categorizes some nations as practicing extreme levels of Internet censorship. Such nations often censor political content and may retaliate against citizens who violate the censorship with imprisonment or other sanctions.
Burma
Burma (also known as Myanmar) is in ONI’s substantial category and is on the RSF’s internet enemy list. Internet use is so threatening in Burma that even going online is considered a dissident act, thus giving the country a very low penetration rate. The internet is regulated by the Electronic Act which bans the importing and use of a modem without official permission, and the penalty for violating this is a 15 year prison sentence, as it is considered “damaging state security, national unity, culture, the national economy and law and order.” [12]
Burma has banned the websites of political opposition groups, sites relating to human rights, and organizations promoting democracy in Burma.[10] During the 2007 anti-government protests, Burma completely shut down all internet links from its country.[13]
Cuba
Cuba is on ONI's watchlist and on RSF's internet enemy list. According to Reporters Without Borders, Cuba has the lowest ratio of computers per inhabitant in Latin America, and the lowest internet access ratio of all the Western hemisphere.[14] Citizens have to use government controlled "access points", where their activity is monitored through IP blocking, keyword filtering and navigation history checking. The government cites its citizens' access to internet services are limited due to high costs and the American embargo, but there are reports concerning the will of the government to control access to uncensored information both from and to the outer world.[15] The Cuban government continues to imprison independent journalists for contributing reports through the Internet to web sites outside of Cuba.[16]
Salim Lamrani, a professor at Paris Descartes University, has accused Reporters Without Borders with making unsupported and contradictory statements regarding Internet connectivity in Cuba.[17]
Egypt
Egypt is not categorized by the ONI and is on the RSF’s internet enemy list. Due to fears of terrorism, the government increased web surveillance in 2007. To connect to wireless internet in a public place, such as a cybercafé, a person must give up a lot of personal information, such as a phone number or ID #, making it hard for citizens to express themselves freely. [12]
Iran
Iran is in ONI's pervasive category and on RSF's internet enemy list. Iran Internet censorship is delegated to ISPs who attempt to filter contents critical of the government, pornographic websites, political blogs, and especially recently women's rights websites, weblogs, and online magazines.[10][18] Bloggers in Iran have been imprisoned for their Internet activities.[19] Most recently, the Iranian government temporarily blocked access, between 12 May 2006 and January 2009, to video-upload sites such as YouTube.com.[20]. Flickr, which was blocked for almost the same amount of time was opened in February 2009. But after 2009 election protests YouTube, Flicker, Twitter, Facebook and many more websites got blocked again. [citation needed]
North Korea
North Korea is not categorized by ONI but is on RSF's internet enemy list. Only a few thousand citizens in North Korea, representing about 4% of the total population, have access to the Internet, which is heavily censored by the national government.[21] According to the RSF North Korea is a prime example where mediums of communication are controlled by the government. According to the RSF, Internet is the medium most used to the service of the North Korean government to primarily spread propaganda. The North Korean network is monitored heavily with only two websites being hosted under a domain name. All websites are under government control, as is all other media in North Korea.[12]
People's Republic of China
The People's Republic of China is in ONI's pervasive category and is on RSF's internet enemy list. China blocks or filters Internet content relating to Tibetan independence, Taiwan independence, police brutality, the Tiananmen Square protests of 1989, freedom of speech, pornography, some international news sources (such as the VOA), certain religious movements (such as Falun Gong), and many blogging websites. Some 52 cyber dissidents are reportedly imprisoned in China for their online postings.[22]
Syria
Syria has banned websites for political reasons and arrested people accessing them, and is in ONI's pervasive category and is on RSF's internet enemy list. In addition to filtering a wide range of Web content, the Syrian government monitors Internet use very closely and has detained citizens “for expressing their opinions or reporting information online.” Vague and broadly worded laws invite government abuse and have prompted Internet users to engage in self-censoring and self-monitoring to avoid the state’s ambiguous grounds for arrest.[10][23]
Tunisia
Tunisia is in ONI's pervasive category and is on RSF's internet enemy list. Tunisia has blocked thousands of websites (such as pornography, mail, search engine cached pages, online documents conversion and translation services) and peer-to-peer and FTP transfer using a transparent proxy and port blocking. Cyber dissidents including pro-democracy lawyer Mohammed Abbou have been jailed by the Tunisian government for their online activities.[24]
Turkmenistan
Turkmenistan is not categorized by the ONI and it is on the RSF’s internet enemy list. Internet usage in Turkmenistan is under tight control by the government. Turkmen got their news through satellite television until 2008 when the government decided to get rid of satellites leaving Internet as the only medium where information could be gathered. Internet is monitored thoroughly by the government as websites ran by human rights organizations and news agencies were blocked. Attempts to get around this censorship could lead to grave consequences [12]
Uzbekistan
Uzbekistan is in ONI's pervasive category and is on RSF's internet enemy list. Uzbekistan prevents access to websites regarding banned Islamic movements, independent media, NGOs, and material critical of the government's human rights violations.[10] Some Internet cafes in the capital have posted warnings that users will be fined for viewing pornographic websites or website containing banned political material.[25]
Vietnam
Vietnam is in ONI's pervasive category and is on RSF's internet enemy list. The main networks in Vietnam prevent access to websites critical of the Vietnamese government, expatriate political parties, and international human rights organizations, among others.[10] Online police reportedly monitor Internet cafes and cyber dissidents have been imprisoned for advocating democracy.[26]
Substantial
Bahrain
![](http://upload.wikimedia.org/wikipedia/en/thumb/4/4f/Batelco.blocked.png/220px-Batelco.blocked.png)
On 5 January 2009 the Ministry of Culture and Information issued an order (Resolution No 1 of 2009)[27] pursuant to the Telecommunications Law and Press and Publications Law of Bahrain that regulates the blocking and unblocking of websites. This resolution requires all ISPs - among other things - to procure and install a website blocking software solution chosen by the Ministry. The Telecommunications Regulatory Authority (“TRA”) assisted the Ministry of Culture and Information in the execution of the said Resolution by coordinating the procurement of the unified website blocking software solution. This software solution is operated solely by the Ministry of Information and Culture and neither the TRA nor ISPs have any control over sites that are blocked or unblocked.
South Korea
South Korea is in ONI's substantial category but is not on RSF's internet enemy list. South Korea's internet censorship policy is highly political and particularly strong toward suppressing anonymity in the Korean internet. In 2007, numerous bloggers were censored and their posts deleted by police for expressing criticism of, or even support for, presidential candidates. This even lead to some bloggers being arrested by the police.[28] Subsequently in 2008, just before a new presidential election, new legislation that required all major internet portal sites to require identity verification of their users was put into effect. This applies to all users who add any publicly viewable content. For example, to post a comment on a news article, a user registration and citizen identity number verification is required. For foreigners who do not have such numbers, a copy of passport must be faxed and verified. Although this law was initially met with public outcry, as of 2008, most of the major portals, including Daum, Naver, Nate, and Yahoo Korea, enforce such verification before the user can post any material that is publicly viewable.[citation needed]
Also, South Korea has banned at least 31 sites considered sympathetic to North Korea through the use of IP blocking.[10] Moreover, They started to block illegal websites such as unrated games, pornography, gambling, etc, since 2008. Attempts to access these sites are automatically redirected to the warning page showing "This site is legally blocked by the government regulations."[citation needed]
Furthermore, search engines are required to verify age for some keywords deemed inappropriate for minors. For such keywords, age verification using national identity number is required. For foreigners, a copy of passport must be faxed to verify the age. As of 2008, practically all large search engine companies in South Korea, including foreign-owned companies (e.g. Yahoo! Korea), have complied with this legislation.[citation needed] Only Google evades government's legislation. In April 2009 when Communication Commission ordered to put on user verification system at YouTube, Google Korea blocked video uploading from user whose country setting is Korean[29].
Saudi Arabia
Saudi Arabia is in ONI's substantial category and is on RSF's internet enemy list. Saudi Arabia directs all international Internet traffic through a proxy farm located in King Abdulaziz City for Science & Technology. Content filtering is implemented there using software by Secure Computing.[30] Additionally, a number of sites are blocked according to two lists maintained by the Internet Services Unit (ISU):[31] one containing "immoral" (mostly pornographic) sites, the other based on directions from a security committee run by the Ministry of Interior (including sites critical of the Saudi government). Citizens are encouraged to actively report "immoral" sites for blocking, using a provided Web form. The legal basis for content-filtering is the resolution by Council of Ministers dated 12 February 2001.[32] According to a study carried out in 2004 by the OpenNet Initiative:
The most aggressive censorship focused on pornography, drug use, gambling, religious conversion of Muslims, and filtering circumvention tools.[30]
See the report by Harvard University's Law School on Documentation of Internet Filtering in Saudi Arabia.
United Arab Emirates
The United Arab Emirates is in ONI's substantial category and is not on RSF's internet enemy list. The United Arab Emirates forcibly censors the Internet using Secure Computing's solution. The nation's ISPs Etisalat and du (telco) ban pornography, politically sensitive material, and anything against the perceived moral values of the UAE. All or most VoIP services are blocked.
Yemen
Yemen is in ONI's substantial category and is not on RSF's internet enemy list. Yemen's two ISPs block access to contents falling under the categories of gambling, adult contents, and sex education as well as material seeking to convert Muslims to other religions.[10]
Nominal and others
Australia
Australia is in ONI's nominal category as of 2008. It does not allow content that would be classified "RC" (Refused Classification or banned) or "X18+" (hardcore non-violent pornography) to be hosted within Australia and considers such content "prohibited"/"potentially prohibited" outside Australia; it also requires most other age-restricted content sites to verify a user's age before allowing access. Since January 2008 material that would be likely to be classified "R18+" or "MA15+" and which is not behind such an age verification service (and, for MA15+, which also meets other criteria such as provided for profit, or contains certain media types) also fits the category of "prohibited" or "potentially prohibited". The regulator ACMA can order local sites which do not comply taken down, and overseas sites added to a blacklist provided to makers of PC-based filtering software. The list itself and associated documentation was specially exempted from Freedom of Information laws under the previous Howard government.
Identification of these "prohibited" or "potentially prohibited" items appears to be done mainly as a response to individual complaints rather than by any attempt to pre-emptively classify sites or pages. In addition, certain addresses (mostly of child porn) also come from international and local law enforcement and related sources. The number of items on the prohibited blacklist was in the range of 1,000 to 1,300 in late 2008 and early 2009, with roughly 32% classified as "child abuse material and child sexual abuse material"[33].
The Australian Labor Party has a policy of mandatory blocking, at the ISP level, of material on the ACMA blacklist, as well as providing a second level of opt-out "clean feed" which would also block adult content and an unknown number of other categories.[34] As of 2008 this policy has been outlined, but not implemented, and there has been significant opposition to it.[35] In March 2009, the ACMA "blacklist" was leaked, revealing several innocent sites which were included in error.
Belgium
Belgian internet providers Belgacom, Telenet, Base, Scarlet, EDPnet, Dommel, Proximus, Mobistar, Mobile Vikings, Tele2, and Versatel have started filtering several websites on DNS level since April 2009[36]. People who browse the internet using one of these providers and hit a blocked website are redirected to a page that claims that the content of the website is illegal under Belgian law and therefore blocked[37].
Brazil
Brazilian legislation restricts the freedom of expression (Paim Law), directed especially to publications considered racist (such as neo-nazi sites). The Brazilian Constitution also prohibits anonymity of journalists.
Canada
Canada is in ONI's nominal category and is not on RSF's internet enemy list. In a few cases, information which the government is actively attempting to keep out of Canadian broadcast and print media (such as names of young offenders or information on criminal trials subject to publication bans) is available to Canadian users via Internet from sites hosted outside Canada.
Project Cleanfeed Canada (cybertip.ca) decides what sites are child pornographic in nature and transmits those lists to the voluntarily participating ISPs who can then block the pages for their users. However, some argue that they are accountable to no one and could be adding non pornographic sites to their list without public knowledge.[citation needed]
Chile
Chile is not categorized by ONI and is not on RSF's internet enemy list and it's considered one of the most liberal countries in terms of internet freedom in Latin America. Many educational institutions (universities and schools) block the access to websites like YouTube, Fotolog, Flickr, Blogger, Rapidshare, Twitter and Facebook, depending of the institution; in some cases also popular portals like Terra.cl, LUN.com, EMOL.com are also blocked; pornography, specially any kind of child pornographic website is blocked.[38] The Chilean Government also block the access in their computers to blogs or electronic versions of the local newspapers with opinions against the Government or the ruling coalition, for example, during the first days of Transantiago or the 2006 Student Protests or the Chile-Microsoft relationship[citation needed]. Some local ISP also block the access to websites with contents against them or any kind of policy promoted by them[citation needed].
Colombia
Colombia blocks several websites as part of its Internet Sano program.
Czech Republic
Since 2008, mobile operators T-mobile[39] and Vodafone [40][41] pass mobile and fixed Internet traffic through Cleanfeed which uses data provided by the Internet Watch Foundation to identify pages believed to contain indecent photographs of children, and racist materials.
On August 13 2009, Telefónica O2 Czech Republic, Czech DSL incumbent and mobile operator, started to block access to sites listed by Internet Watch Foundation. Operator said he wanted to replace the list with data provided by Czech Police. [42] Blocking system roll-out attracted public attention due to serious network service difficulties and many innocent sites mistakenly blocked[43]. The concrete blocking implementation is unknown but it's believed recursive DNS servers provided by the operator to his customers have been modified to return fake answers diverting consequent TCP connections to HTTP firewall.[44]
Denmark
Denmark is not categorized by ONI and is not on RSF's internet enemy list. Denmark's biggest Internet service provider TDC A/S launched a DNS-based child pornography filter on 18 October 2005 in cooperation with the state police department and Save the Children, a charity organisation. Since then, all major providers have joined and as of May 2006, 98% of the Danish Internet users are restricted by the filter.[45] The filter caused some controversy in March 2006, when a legal sex site named Bizar.dk was caught in the filter, sparking discussion about the reliability, accuracy and credibility of the filter.[46] Also, as of 18 October 2005, TDC A/S has blocked access to AllOfMP3.com, a popular MP3 download site, through DNS filtering.[47]
4 February 2008 a Danish court has ordered the Danish ISP Tele2 to shutdown access to the filesharing site thepiratebay.org for all its Danish users.[48]
On 23 December 2008, the list of 3,863 sites filtered in Denmark was released by Wikileaks.[49]
Fiji
Fiji is not categorized by ONI and is not on RSF's internet enemy list. In May 2007 it was reported that the military in Fiji had blocked access to blogs critical of the regime.[50]
Finland
Finland is not categorized by ONI and is not on RSF's internet enemy list. Following a "voluntary law" [51] enacted by Finnish parliament in 1 January 2007, most of the Finland's major Internet service providers decided on 22 November 2006 to begin filtering child pornography and first ISPs started filtering on January 2008. The Ministry of Communications has commented that filtering is voluntary for ISPs as long as they do not refuse. The blacklist is provided by Finnish police and should contain only foreign sites. Technically filtering was planned to be URI based like the United Kingdom's Cleanfeed, but so far implementations have been DNS based.
A majority of these censored Internet sites, however, do not actually seem to be censored by the Finnish ISPs due to actual child pornography, but due to "normal" adult pornography instead. Most of the known sites are also located in EU or United States where child pornography is strictly illegal anyway. Two-thirds of the Finnish internet censorship list of the filtered domains were collected on lapsiporno.info,[52] the homepage of Matti Nikki, a Finnish activist criticizing Internet censorship in the European Union and especially in Finland. On 12 February 2008, Nikki's page was also added to National Bureau of Investigation's blacklist (Wikinews article). As the list was compiled using links from pornography sites, this list does not tell anything about the last third of the blocked sites.
At September 2008 problems with accuracy continued, when websites of main international standards organization for World Wide Web W3C was briefly blacklisted as childporn by mistake.[53]
More recently, a government-sponsored report has considered establishing similar filtering in order to curb online gambling.[54]
After investigation of complaints about how the law on filtering child pornography has been implemented and the actions of the police the vice Parliamentary Ombudsman concludes (29.5.2009) that the police has followed the law and that most sites on the list did have material that could be classified as child pornography at the time they were investigated by the police. He also found that the law is somewhat unclear and that its effect on free speech is problematic and recommends these matters be considered when the law is overseen.[55]
France
France is in ONI's watchlist and is not on RSF's internet enemy list. French courts demanded Yahoo! block Nazi material in the case LICRA vs. Yahoo. The case is currently[citation needed] on appeal for an en banc rehearing.
The Hadopi law, enacted in 2009, allows disconnecting from the Internet users that have been caught illegally downloading copyrighted content, or failing to secure their system again such illegal downloads; as of August 2009, this law is to be supplemented by a Hadopi2 law. The LOPPSI law, brought before Parliament in 2009, will authorize a blacklist of sites providing child pornography, established by the Ministry of the Interior, which Internet service providers will have to block.
Germany
Ghana
Ghana is not categorized by ONI and is not on RSF's internet enemy list. In 2002 the government of Ghana censored internet media coverage of tribal violence in Northern Ghana.[56]
Ireland
India
India is in ONI's nominal category and is not on RSF's internet enemy list. As of July 2006[update] the Indian government has directed ISPs to block seventeen websites, including some hosted on the Geocities, Blogspot and Typepad domains. Initial implementation difficulties led to these domains being blocked entirely.[57][58] Access to sites on these domains other than the specifically banned ones was restored by most ISPs after about a week.[59] The first documented incident of Internet censorship in India was the Yahoo! Groups ban of 23 September 2003. Kynhun, a Yahoo! group linked to the outlawed "Hynniewtrep National Liberation Council", a minor separatist group, was ordered banned by the Department of Telecommunications. Difficulties in implementing the ban by the ISP's ultimately led to all Yahoo! groups being banned for a period of about two weeks.
Recently, Indian law enforcement has entered an agreement with the popular social networking site Orkut to track down what it deems defamatory content which, in their example, includes content critical of Bal Thackeray.[60]
India is also looking to block Google Maps due to the Mumbai attacks.
Israel
Israel is not categorized by ONI and is not on RSF's internet enemy list. The Orthodox Jewish parties in Israel proposed an internet censorship legislation would only allow access to adult-content Internet sites for users who identify themselves as adults and request not to be subject to filtering. In 27/02/2008 the law passed in its first of three votes required[61], however it has been rejected by the government's legislation committee on 12/07/2009.[62] Israeli laws regarding the holocaust denial [63] apply to the Internet as well as to traditional media. Sites which deny the holocaust cannot be hosted in Israel and Israelis who attempt to use the Internet for the purposes of holocaust denial face arrest and imprisonment.
Italy
Italy is not categorized by ONI and is not on RSF's internet enemy list. Italy bans the use of foreign bookmakers over the Internet by mandating certain edits to DNS host files of Italian ISPs.[64][65]. Italy is also blocking access to websites containing child pornography. [66] From August 2008, Italy is blocking also The Pirate Bay website[67][68], basing this censorship on a law on electronic commerce and it's the absolutely first in Italy making a block not only for the present, but also for the future[69]. On this last block, a consumer-association, Altroconsumo, have announced reappeal.
Jordan
Jordan is not on RSF's internet enemy list and censorship is relatively light. Access to Internet content in the Hashemite Kingdom of Jordan remains largely unfettered, with filtering selectively applied to only a small number of sites. However, media laws and regulations encourage some measure of self-censorship in cyberspace, and citizens have reportedly been questioned and arrested for Web content they have authored. Censorship in Jordan is mainly focused on political issues that might be seen as a threat to national security due to the nation's close proximity to regional hotspots like Israel, Iraq, Lebanon, and the Palestinian territories. Jordan, unlike most of its neighbors, has a free and an advanced telecommunications sector. [70]
Mexico
In May 2009, the Mexican Federal Electoral Institute (IFE), asked Youtube to remove a parody of Fidel Herrera, governor of the state of Veracruz. Negative advertising in political campaigns is prohibited by present law, although the video appears to be made by a regular citizen which would make it legal. It was the first time a Mexican institution intervened directly with the Internet. However, Mexico has yet to censor any sites.
Morocco
Morocco is in ONI's watchlist and is not on RSF's internet enemy list. As of March 2006, Morocco had blocked access to a few blogging sites, such as LiveJournal. Reporters Without Borders says that Morocco now censors all political websites advocating Western Sahara's independence, however many Western Sahara-related blogs are still accessible. Google Earth has also been added to the list of filtered Web sites in Morocco. In 2007 Morocco's main telecommunication operator Maroc Telecom also blocked access to YouTube for nearly a month, without giving any reason.[citation needed]
Netherlands
Since 2007 in the Netherlands one major ISP, UPC Netherlands, blocks access on DNS level to sites authorities claim are known to provide child pornography. In the second quarter of 2008 all major Dutch ISP's have agreed with Ernst Hirsch Ballin of the Ministry of Justice to also block all the sites that are on the list. The blacklist is compiled by the National Police Forces (KLPD) [71]. Ernst Hirsch Ballin has said [72] that at the moment 150 websites are blocked. It contains no websites that are hosted in EU countries and they are checked once every 2 months by Productteam Bestrijding Kinderpornografie. Providers will not be forced to use it since that would be unconstitutional according to a research done by the governmental Scientific Research- and Documentation Center (WODC)[73] commissioned by the Ministry of Justice. As of 2009 the only providers that use the filter are UPC and two small providers, Scarlet and Kliksafe. The providers that have been positive about a non-mandatory filter do not have it in use.
Norway
Norway is in ONI's watchlist and is not on RSF's internet enemy list. Norway's major Internet service providers have a DNS filter which blocks access to sites authorities claim are known to provide child pornography,[74] similar to Denmark's filter. A list claimed to be the Norwegian DNS blacklist was published at Wikileaks in March 2009[75]. The minister of justice, Knut Storberget, sent a letter threatening ISPs with a law compelling them to use the filter should they refuse to do so voluntarily (dated August 29, 2008).[76]
Pakistan
Pakistan is in ONI's watchlist and is not on RSF's internet enemy list. Pakistan has blocked access to websites critical of the government. Currently[citation needed], the government has blocked blogs hosted on Blogspot.com. A ban on pornographic websites has also been enacted.[citation needed]. Websites promoting Balochistan and Sindh nationalism or documenting human rights abuses in those places have also been banned.[2]
Since 2007, No material has been reported are banned or censored including pornographic material.
2008, Youtube was banned by the government and enforced throughout the country due to the launch of an Anti-Islamic video being posted. Ban was lifted only after 5 days.
Poland
Although in Poland the Internet is basically free from state interventions there is a huge problem with portal censorship. Most popular forums are heavily manipulated by their managements through constant, organized sending posts that reflect preferred views or simply heat up the atmosphere to increase the number of clicks. This kind of manipulations are dangerous to freedom of speech because they hamper discussions between people of different outlooks and falsify the representativeness of a forum.
Russia
Russia is in ONI's watchlist and is not on RSF's internet enemy list. Russia pressured Lithuania into shutting down the Kavkaz-Center website, a site that hosts videos on attacks on Russian forces in Chechnya, and reports on the Second Chechen War from a Chechen separatist perspective.[10] In February 2008, it became known that six Russian internet providers with ties to the government were blocking access to an opposition aggregate news site. After this became public, the biggest of these companies dropped the block and explained that it was "testing content filters". The other five blocks remain in place.[77]

In 2007 a lawsuit against Savva Terentiev, a musician from Syktyvkar, was started because of a commentary in a LiveJournal blog, in which he sharply criticised local police forces. He was accused of "provoking antagonism between social groups". Although several philological expert examinations of the text denied this accusations, arguing that this was just a relational expression, he received a one-year suspended jail sentence.[78] Censorship of health-related issues on the Internet in Russia mounts, and encompasses the entire world to English Wikipedia and Wikimedia Foundation as well. It violates basic human rights of Russian-reading audience on health and freedom of expression.
Singapore
Singapore is in ONI's nominal category and is not on RSF's internet enemy list. In Singapore, three people were arrested and charged with sedition for posting racist comments on the Internet, of which two have been sentenced to imprisonment.[citation needed] Some ISPs also block internet content related to recreational drug use. Singapore's government-run Media Development Authority maintains a confidential list of blocked websites that are inaccessible within the country. The Media Development Agency exerts control over Singapore's three ISPs to ensure that blocked content is entirely inaccessible.
Sweden
Sweden is not categorized by ONI and is not on RSF's internet enemy list. Sweden's major Internet service providers have a DNS filter which blocks access to sites authorities claim are known to provide child pornography, similar to Denmark's filter. A partial sample of the Swedish internet censorship list can be seen at a Finnish site criticizing internet censorship. The Swedish police are responsible for updating this list of forbidden Internet sites. On 6 July, Swedish police said that there is material with child pornography available on torrents linked to from the torrent tracker site Pirate Bay and said it would be included in the list of forbidden Internet sites. This, however, did not happen as the police claimed the illegal material had been removed from the site. Police never specified what the illegal content was on TPB. This came with criticism and accusations that the intended The Pirate Bay's censorship was political in nature.
Thailand
Thailand is in ONI's nominal category and is not on RSF's internet enemy list. Significant efforts have been made in Thailand to oppose sites that are representing illegal activities. Activities such as gambling, drug usage and pornography are strictly banned, using DNS control in Thailand and, more effectively, a transparent proxy. This makes the website appear to be inaccessible. Also, the government has banned sites that discuss circumventing Internet censorship.[citation needed]
Turkey
Many minor and major websites in Turkey have been subject to censorship until now, including the oldest and most popular Turkish social blogging community Sourtimes and widely popular poetry and literature community Antoloji.com. On 6 March 2007, the government of Turkey blocked access to the video-upload site YouTube.com, with the following statement parked on the domain: "Access to www.youtube.com site has been suspended in accordance with decision no: 2007/384 dated 06.03.2007 of Istanbul First Criminal Peace Court."[79] The ban was met with widespread protests and lifted two days later. Youtube was banned again in 12.03.2008 with decision no 2008/251, which was then soon lifted. As of August 2008, Youtube is still banned in the country since 5th of May 2008, due to two court decisions.
Beside Youtube, 853 minor and major websites are currently banned in Turkey, including the widely popular blogging site Wordpress.com, which has been banned since August 2007 complete with all subdomains. As of October 2008, Blogger is banned too. Other prominent websites currently on ban in Turkey include Youporn, The Pirate Bay, Megaupload, Deezer, Virb, Dailymotion, Google Groups, Tagged, Netlog, Slide, GeoCities, CareerBuilder ,Alibaba and in 24 October 2008 Blogspot. Ironically, The Internet Movie Database had been lucky enough to get away from being censored due to a misspelling of its domain, resulting in a futile ban on www.imbd.com. [80]
As of September 2008, Turkey filters access to prominent evolutionary biologist Richard Dawkins' Web site. The filtering was in response to a complaint from Turkish creationist Adnan Oktar (nom de plume Harun Yahya). Oktar is also behind the filtering of Wordpress and Google Groups.
Turkey is not categorized by ONI and is not on RSF's internet enemy list. However, beside the old media control and censorship association RTÜK, a new governmental association has been recently established just for Internet control and censorship without prior court judgement as it was before.[citation needed] According to the 5651st law of Turkish Penal Code, all media including websites directing people to suicide, child abuse, drugs, pornography, prostitution, insulting and gambling are forbidden. Turkish Telecommute Foundation has also a website for public reports[81]. Nevertheless due to the public profile of the major websites currently on ban; juridicial, technical and ethical arguments for their complete censoring have been painfully lacking, which resulted in extensive piercing of the prohibitions via the use of proxies or change of DNS servers.
United Kingdom
The United Kingdom is in ONI's watchlist and is not on RSF's internet enemy list. British Telecommunications ISP passes internet traffic through a service called Cleanfeed which uses data provided by the Internet Watch Foundation to identify pages believed to contain indecent photographs of children.[82][83] When such a page is found, the system creates a 'URL not found page' error rather than deliver the actual page or a warning page. Other ISPs use different systems such as WebMinder [3].
United States of America
The United States of America is in ONI's nominal category and is not on RSF's internet enemy list.
Although some content is illegal and can be taken down, e.g. child pornography, there is no nationwide filtering of (foreign) content. This would be considered a violation of the First Amendment to the United States Constitution, especially since no filter is perfect and some overblocking would occur.
In 1996 the United States enacted the Communications Decency Act, which severely restricted online speech that could potentially be seen by a minor – which, it was argued, was most of online speech. Free speech advocates, however, managed to have most of the act overturned by the courts. The Digital Millennium Copyright Act criminalizes the discussion and dissemination of technology that could be used to circumvent copyright protection mechanisms, and makes it easier to act against alleged copyright infringement on the Internet. Many school districts in the United States frequently censor material deemed inappropriate for the school setting. In 2000, the U.S. Congress passed the Children's Internet Protection Act (CIPA) which requires schools and public libraries receiving federal funding to install internet filters or blocking software.[84] Congress is also considering legislation to require schools, some businesses and libraries to block access to social networking websites, The Deleting Online Predators Act. Opponents of Internet censorship argue that the free speech provisions of the First Amendment bars the government from any law or regulation that censors the Internet.[85]
A 4 January 2007 restraining order issued by U.S. District Court Judge Jack B. Weinstein forbade a large number of activists in the psychiatric survivors movement from posting links on their websites to ostensibly leaked documents which purportedly show that Eli Lilly and Company intentionally withheld information as to the lethal side-effects of Zyprexa. The Electronic Frontier Foundation appealed this as prior restraint on the right to link to and post documents, saying that citizen-journalists should have the same First Amendment rights as major media outlets.[86] It was later held that the judgement was unenforcable, though First Amendment claims were rejected.[87]
The Department of Defense filters certain IP addresses. The US military's filtering policy is laid out in a report to congress entitled Department of Defense Personnel Access to the Internet.
Portal censorship
Major portals occasionally exclude web sites that they would ordinarily include. This renders a site invisible to people who do not know where to find it. When a major portal does this, it has a similar effect as censorship. Sometimes this exclusion is done to satisfy a legal or other requirement, other times it is purely at the discretion of the portal.
Examples
- Google.de and Google.fr remove Neo-Nazi and other listings in compliance with German and French law.[88]
Major web portal official statements on site removal
![]() | This section needs expansion. You can help by adding to it. (June 2008) |
- Google:[89] "Google may temporarily or permanently remove sites from its index and search results if it believes it is obligated to do so by law, if the sites do not meet Google's quality guidelines, or for other reasons, such as if the sites detract from users' ability to locate relevant information."
- Yahoo!:[90] Yahoo!’s terms of service state that they reserve the right to “pre-screen, refuse or remove” any content that they feel violates the terms of service or deem distasteful, however removing information is never obligatory. Yahoo! also does not reserve the right to pre-screen any information.
Commonly targeted websites
- Pornographic, pedophile-related, and other websites considered objectionable (see also CIRCAMP)
- Social networks (e.g. Facebook, MySpace and Twitter)
- Wikipedia
- Wikileaks[91]
- Political blogs[92]
- YouTube[93]
- Nazi and similar websites — particularly in France and Germany[94]
- Religious websites
- Google - particularly in mainland China and Cuba[95]
- Censorship-circumvention websites
- Foreign websites
Fiction works
Internet, censorship and freedom of speech are the principal subjects of the dystopic theatrical play Fahrenheit 56K[96]. The action pass on a fictional dictatorship where dissidents expose their wailings against the Party through Internet.
