A fabricated Wikipedia page claiming that Jason R. Day is a real British performance artist and impersonator who disappeared in 2012 is false; Day is an AI-generated character intended to satirize University of Cambridge professor Jason Arday. The fake page appeared in a post by the @ByrneHobart account on X on Aug. 3, 2026, and included an image flagged "Made with AI" with the icon for Google Gemini. The page stated Day was born on 17 March 1982 in Bristol, England, studied at Jesus College, Cambridge, was expelled in 2003, and vanished on 1 January 2012 after posting a video. The satirical page targets Arday, a British sociologist who became the youngest Black professor ever appointed at the University of Cambridge in 2023. Arday has been accused of plagiarism and of falsely exaggerating his achievements, including a claim to hold a "visiting professor" position at the University of Glasgow that was later denied by a University spokesperson in a news article. The poster on X highlighted that retweets cut off the "Made with AI" label, calling it an "incredible engagement hack."
