Gripe site
A gripe site is a type of website that is dedicated to criticism of or complaint about a certain individual, sometimes constructive and other times for the purpose of lampooning the target. That targeted individual could be a person, place, politician, corporation, institution, or something else. These are often created by less affluent people to target powerful people or groups because space is cheap on the Internet.
In an attempt to shut down a gripe site, companies have sued the gripe site owner alleging defamation, trademark infringement, trademark dilution, libel, and copyright infringement.
