PhantomL0rd
In 2016, PhantomL0rd was found to be involved in Counter-Strike: Global Offensive bet rigging and being an undisclosed partial owner of CSGOShuffle, a skin betting website.

Sorry, I meant to say that he was allegedly a total douche canoe that scammed numerous people out of money by lying to them. To make a long story short, PhantomL0rd was banned from Twitch after news broke about his "allegedly" douchey actions.

Fast-forward now to 2018 and PhantomL0rd is now suing Twitch for "breach of contract, intentional interference with contractual relations, and intentional and negligent misrepresentation in removing him from their platform." Basically, he's running out of money and he's throwing a Hail Mary.
According to the suit, Twitch employees repeatedly told Varga that his content was not in breach of the terms of service—specifically his gambling on stream. Varga also alleges that his partnership agreement with Twitch required notice of any terms of service breach, and a 30-day grace period to correct the violation.

Varga believed gambling to be permissible on the platform based on communication with partnerships manager Jason "Opie" Babo. The filing includes messages from Babo in May 2016, where Babo expressed confusion at the current rules around gambling content on Twitch but did suggest that Varga not gamble for more than a few minutes at a time to avoid issues. Babo has since left Twitch, joining ESL in December 2017.

According to dotesports, the lawsuit fails to mention that Twitch clarified its rules on July 14, 2016. The updated rules, at that time, said that any content which breached Valve's rules (this includes skin gambling using the Steam API) would be in breach of the terms of service. James "PhantomL0rd" Varga was banned on July 19, 2016.

Ooooh. Ouch! Uh, good luck on that PhantomL0rd?
