• Illustration — Knapp (third from left) at a Wikipedia training session in 2011 Knapp announced his millionth edit to Wikipedia on April 19, 2012. At the time, he had been submitting on average 385 edits a day since signing up in March 2005; about his performance he said: "Being suddenly and involuntarily unemployed will do that to you." Margaret Ferguson, an associate professor of political science at Indiana University–Purdue University Indianapolis and one of Knapp's professors, said she was not surprised by his dedication to editing Wikipedia. In 2012, Wikipedia co-founder Jimmy Wales congratulated Knapp for his work and presented him with the site's highest award for his achievement by declaring that April 20 would be Justin Knapp Day. His Wikipedia username, Koavf, was chosen as an acronym for "King of all Vext Fans", a reference to a contest Knapp entered for Vext in the 1990s. Knapp was a significant contributor to Wikipedia's bibliography of George Orwell, and he has also made many edits involving the categorization of albums through Wikipedia's category structure. In 2012, the Indianapolis Star reported that Knapp sometimes edited Wikipedia for as many as 16 hours a day. In a 2014 interview with Business Insider, Knapp said that "there is no typical day" with regard to his Wikipedia editing, and that his "go-to edits are small style and typo fixes". He also argued that the declining number of Wikipedia editors is "not necessarily a problem". Knapp, who has been blocked from editing multiple times, said in a 2015 interview with technology journalist Zachary Crockett that he "wouldn't be surprised if I've been banned more than anyone". In July 2024, he was banned from the English Wikipedia following a community discussion.
