[4][5] Various styles of humor are used as vehicles for parody, from pointed satire to light sarcasm, along with structured in-jokes and frequent non sequiturs.

The site has attracted media attention for its articles on controversial subjects including religion, prominent people, places, politics, and pseudoscience.

In May 2018, Fandom dropped support for the Monobook skin that its Uncyclopedia site had used to mimic Wikipedia, claiming this was necessary to achieve GDPR compliance,[9] and warned that local work-arounds could not be extended to new visitors and editors by default.

[10] Since all Uncyclopedias split off or were removed from Fandom, they mostly switched to using Vector instead (with MinervaNeue on mobile), in order to continue parodying Wikipedia.

They contain interlanguage links to each other, but there is no global governing organization comparable to the Wikimedia Foundation that oversees Wikipedia as well as its sister projects.

In 2012, as a parody of Wikipedia's black-out protest against the Stop Online Piracy Act (SOPA) et al., Uncyclopedia blocked all content for a day with a notice claiming to support the bills.

[21] For one week in 2013, the Wikia fork interrupted viewing with a claim that the site was unavailable, spoofing a notice on the NASA website during the United States federal government shutdown of 2013.

[citation needed] As well as housing many articles designed to satirize Wikipedia-style content, Uncyclopedia contains several secondary projects (known as "UnProjects").

Uncyclopedia has been referenced in several well-known news publications from around the world, in addition to numerous local and regional newspapers and periodicals.

[28] In addition to articles about specific entries on the wiki, several papers speak of the website in general – usually in a section devoted to technology or the Internet.

[34] At various times, articles on Uncyclopedia have been subject to criticism from King's College (School, Auckland)[35] the North-West Evening Mail,[36] Northern Irish politician James McCarry,[37] civic leaders of Telford, Shropshire, UK,[38] the Sioux City Journal,[39] Hawke's Bay Today,[40] and Lochaber News.

[41] In January 2008, the Malaysian Internal Security Ministry issued a directive alerting newspaper editors not to trust Uncyclopedia.

[45][46] In November 2012, the page "HowTo:Commit suicide" on Absurdopedia, the Russian-language Uncyclopedia, was legally prohibited by the Russian Federal Service for Supervision of Consumer Rights Protection and Human Welfare (Rospotrebnadzor).

Absurdopedia administrator Edward Chernenko unsuccessfully sued them under his right to science and culture guaranteed by the Russian Constitution.

During the proceedings, the Russian government and its experts claimed that Absurdopedia is intentionally trying to increase the number of child suicides in Russia by providing children with instructions for killing themselves.
