YouTuber Karl Jobst has filed a lawsuit against former Donkey Kong high score record holder Billy Mitchell, accusing him of 'unauthorized appropriation of name or likeness,' 'defamation,' and 'intentional infliction of emotional distress.' Jobst, who is representing himself as a 'Pro Se Plaintiff,' previously lost a defamation suit against Mitchell in Australia. The new lawsuit cites several of Mitchell's social media posts as evidence of defamation, though it does not mention the suicide of YouTuber Apollo Legend, which was a key part of the previous case.

Why it matters

The ongoing legal battle between Jobst and Mitchell highlights the intense rivalries and accusations that can arise within the competitive gaming community. The case also raises questions about the responsibilities of content creators when making claims about other individuals, and the potential consequences of providing misleading information to supporters through crowdfunding campaigns.

The details

In the latest lawsuit, filed in the United States District Court for the Southern District of Florida, Jobst accuses Mitchell of 'unauthorized appropriation of name or likeness,' 'defamation,' and 'intentional infliction of emotional distress.' Jobst cites several of Mitchell's social media posts, including one in which Mitchell states that Jobst 'SCAMMED $200,000, WENT BANKRUPT, AND LOST EVERY SHRED OF CREDIBILITY.'
