An anonymous post is an entry on a bulletin board system, Internet forum, or other discussion forums without a screen name or more commonly by using a non-identifiable pseudonym. Some online forums do not allow such posts, requiring users to be registered either under their real name or utilizing a pseudonym. Some may allow anonymous posts, but discourage them by referring to such posters as "anonymous cowards", such as in the case of Slashdot. Others like JuicyCampus, AutoAdmit, 2channel, and other Futaba-based image boards (such as 4chan) thrive on anonymity. Users of 4chan, in particular, interact in an anonymous and ephemeral environment that facilitates rapid generation of new memes.
 History of online anonymity
Online anonymity can be traced to Usenet newsgroups in the late 1990s where the notion of using invalid emails for posting to newsgroups was introduced. This was primarily used for discussion on newsgroups pertaining to certain sensitive topics. There was also the introduction of anonymous remailers which were capable of stripping away the sender's address from mail packets before sending them to the receiver. Online services which facilitated anonymous posting sprang up around mid-1992, originating with the cypherpunk group.
The precursor to internet forums like 2channel and 4chan were textboards like Ayashii World and Amezou World that provided the ability for anonymous posts in Japan. These "large-scale anonymous textboards" were inspired by the Usenet culture and were primarily focused on technology, unlike their descendents.
 Levels of anonymity
Anonymity on the Internet can pertain to both the utilization of pseudonyms or requiring no authentication at all (also called "perfect anonymity") for posting on a website. Online anonymity is also limited by IP addresses. For example, WikiScanner associates anonymous Wikipedia edits with the IP address that made the change and tries to identify the entity that owns the IP address. On other websites, IP addresses may not be publicly available, but they can be obtained from the website administrators only through legal intervention. They might not always be traceable to the poster.
 Techniques for anonymous posting
Utilizing pseudonyms allow people to post without revealing their real identity. Pseudonyms however, are still prone to being tracked to the user's IP address. To avoid being tracked to an IP address, it is possible to post via a public computer where the IP address would usually be under the purview of the public workspace such as a coffee shop, and hence cannot be traced to the individual user.
There are services described as anonymizers which aim to provide users the ability to post anonymously by hiding their identifying information. Anonymizers are essentially proxy servers which act as an intermediary between the user who wants to post anonymously and the website which logs user information such as IP addresses. The proxy server is the only computer in this network which is aware of the user's information and provides its own information to anonymize the poster. Examples of such anonymizers include I2P and Tor, which employ techniques such as onion and garlic routing to provide enhanced encryption to messages that travel through multiple proxy servers.
 Legal standards and regulations
The revised draft of the Chinese government's "Internet Information Services" proposes that, "Internet information service providers, including microblogs, forums, and blogs, that allow users to post information on the Internet should ensure users are registered with their real identities".
 The Philippines
The government of Philippines approved the Cybercrime Prevention Act on September 12, 2012, which among other things gives the Philippine Department of Justice to, "block access to "computer data" that is in violation of the Act; in other words, a website hosting criminally libelous speech could be shut down without a court order".
 United Kingdom
The UK government's bill titled the "Defamation Bill", proposed on May 10, 2012, seeks to allow website operators the ability to hand over information of posters who have posted an allegedly defamatory statement on the website. The compliance seeks to provide hosts of an online community to escape libel claims as long as they agree to provide details of relatively anonymous posters upon request. The bill which is still under process has come under criticism for not being detailed enough to provide security to the more positive aspects of anonymous posting.
 United States
The right to speak anonymously online is protected, in the United States, by the First Amendment, and various other laws. These laws restrict the ability of the government and civil litigants to obtain the identity of anonymous speakers. The First Amendment says that "Congress shall make no law...abridging the freedom of speech, or of the press". This protection has been interpreted by the U.S. Supreme Court to protect the right to speak anonymously offline.
For example, in McIntyre v. Ohio Elections Commission, the Supreme Court overturned an Ohio law banning the distribution of anonymous election pamphlets, claiming that an "author’s decision to remain anonymous...is an aspect of the freedom of speech protected by the First Amendment" and that "anonymous pamphleteering is not a pernicious, fraudulent practice, but an honorable tradition of advocacy and of dissent", as well as a "shield" against the so-called tyranny of the majority. The Court found that . Various courts have interpreted these offline protections to extend to the online world.
On March 21, 2012, the New York State Senate introduced the bill numbered S.6779 (and A.8668) labeled as the "Internet Protection Act". It proposes the ability of a website administrator of a New York-based website to take down anonymous comments unless the original author of the comment agrees to identify themselves on the post.
 Anonymous posting in online communities
Online communities vary with their stances on anonymous postings. Wikipedia allows anonymous editing in most cases, but does not label users, instead identifying them by their IP addresses, with other editors commonly referring to them with neutral terms such as "anons" or "IPs".
Many online bulletin boards require users to be signed to write—and, in some cases, even to read—posts. 2channel and other Futaba-based image boards take an opposite stance, encouraging the anonymity, and in the case of English-language Futaba-based websites, calling those who use usernames and tripcodes "namefags" and "tripfags", respectively. As required by law, even communities such as 4chan do require the logging of IP addresses of such anonymous posters. Such data however, can only be accessed by the particular site administrator.
 Effects on users
The effects of posting online anonymously has been linked to the online disinhibition effect in users whilst been categorized into either benign or toxic disinhibition. Disinhibition can result in misbehavior, but can also improve user relationships. It may also result in greater disclosure among Internet users, allowing more emotional closeness and openness in a safe social context.
Anonymous computer communication has also been linked to accentuate self-stereotyping. It has however been linked to notable effects in gender differences only when the topic bears similarity and fits with the gender stereotype.
 Effects on online communities
The conditions for deindividuation such as "anonymity, reduced self-awareness, and reduced self-regulation" fosters creations of online communities much in the same way that they might be employed offline. This is evident in proliferation of communities such as Reddit or 4chan which utilize total anonymity or pseudonymity to provide its users the ability to post varied content. The effect of disinhibition has been seen to be beneficial in "advice and discussion threads by providing a cover for more intimate and open conversations".
There is also research suggesting that content that gets posted in such communities also tends to be more deviant in nature than would be otherwise. The ability to post anonymously has also been linked to the proliferation of pornography in newsgroups and other online forums wherein users utilize sophisticated mechanisms such as mentioned in technology.
