League of Legends player banned from Championship Series for 'persistent toxic behavior'

Developer Riot Games' eSports team has banned a player known as IWillDominate from the League of Legends Championship Series for a pattern of "persistent toxic behavior," according to a post on the North American League of Legends forum.

The permanent ban comes as a result of his "persistent tendency to engage in verbal abuse and insults, his lack of cordial demeanor, and his treatment of less-skilled players," according to the published ruling.

IWillDominate is the screen name of Christian Rivera, who played League of Legends on the Team Dignitas professional gaming team. The League of Legends Tribunal System decided his fate. The ruling body "empowers the League of Legends community to regulate the conduct that it considers appropriate and supports the tenets of the Summoner's Code," according to the official FAQ.

"Despite the punishments and official warnings, his harassment score has risen more than 30% from early August to the present date."

The ruling reveals that this was IWillDominate's ninth visit to the Tribunal. He had been punished eight times and received numerous warnings about his behavior both in and outside of the game, to no avail.

"Despite the punishments and official warnings, his harassment score has risen more than 30% from early August to the present date, placing him at the top of the list of North American pro players and among the worst 0.7% of all North American players," the ruling reads.

Riot will also ban all other "existing known accounts used by IWillDominate."

"We've looked at our own game and said 'This is not a great experience and we want to try to handle this problem,'" producer Carl Kwoh told Polygon.
