According to the website of Dynamis LLP law firm, Keith Gill (also known as Roaring Kitty), a US retail investor who became famous for his posts on the social media platforms "X" and Reddit, has been sued for securities fraud in the eastern district of New York, because of the posts he made about his ownership of shares in Gamestop (GME.N) on those platforms. The plaintiff claims that Gill's posts on social media were part of his "pump and dump" scheme. Gill secretly purchased a large number of call options for Gamestop, and used social media to "promote" these assets. He did not disclose his purchase of securities before posting the messages (which made people think he was just considering buying Gamestop for the first time in years), and on June 2, 2024, he disclosed a large number of option positions without disclosing his plan to sell the call options he had recently purchased to the public.
