A gripe site is a type of website devoted to the critique and or mockery of a person, place, politician, corporation, or institution. They are also known as "complaint" or "sucks" sites. The Internet provides a low-cost public platform for anyone, even of modest means, to reach a global audience via a "gripe" website. The web gives ordinary individuals the opportunity to publicly criticise the rich and powerful, including multinational corporations. Time and money is invested in the hope of gaining satisfaction by airing a perceived grievance and embarrassing the party which is the target of the "gripe".
The following definition of a "gripe site" is from comments authored by a notable American lawyer, Paul Levy, and published online by Public Citizen, a Washington, D.C.-based organization founded in 1971 by Ralph Nader: "A 'gripe site' is a web site established to criticize an institution such as a corporation, union, government body, or political figure. Not surprisingly, powerful institutions often do not take kindly to being criticized, and they have invented a variety of ways to try to suppress the speech of their adversaries." Levy is also a lawyer within the associated Public Citizen Litigation Group, another non-profit making organization. He is the founder of the groups “Public Internet Free Speech Project”.
