Disinformation on Wikipedia is the practice of intentionally spreading false information for the purpose of deception and to promote discord. It concerns state-sponsored efforts such as by so-called "Russian troll" accounts, and other countries known to use social media and other outlets for the spread of disinformation. It is distinct from regular propaganda, conflict of interest or vandalism in that it involves state-actors (or state-sponsored or condoned actors) and is a form of information warfare ie. a weapon meant to cause harm.

The purpose of this page is to centrally collect links and information about disinformation as it relates to Wikipedia.

Summary: Russian disinformation trolls used Wikipedia in conjunction with Twitter and Tumblr to promote fake news in 2015. They created a hoax story about a food poisoning attack in New York, then created a Wikipedia page about it (2015 New York poisoned turkey incident), then tweeted about it thousands of times. The fake story was quickly uncovered and a Sock Puppet Investigation blocked 4 accounts. Those accounts were "sleepers" previously making uncontroversial edits while establishing user editing privs. They previously edited articles about Hillary Clinton, the Central Intelligence Agency and American extremist groups.

Summary: Someone from the All-Russia State Television and Radio Broadcasting Company (VGTRK) was caught editing a Russian-language Wikipedia reference to MH17. The edit placed the blame for the downing on Ukraine and deleted any fault of Russia. The edit was caught by a Twitter bot that monitors Wikipedia edits made from Russian government IP addresses.
