Looks like Riot finally swung that Ban Hammer. A statement released by Riot:
Instant Feedback catches the most unsportsmanlike players in League, but some people go out of their way to continue ruining games for the community. Because of a well-documented history of account bans for verbal abuse, intentional feeding, as well as account sharing/purchasing, evasion of sportsmanship systems, and player harassment, we will not allow Tyler1 to hold a League of Legends account, indefinitely. Any account definitively used by him will be banned immediately upon identification.
We know we’re not perfect, and this dragged on too long, but we want you to know when the rare player comes along who’s a genuine jerk, we’ve still got your back."
