Riot Games has suspended a top League of Legends pro for “violations of the Summoner’s Code”.

Team Dignitas member Christian “IWillDominate” Rivera was handed the ban for “persistent toxic behaviour”, and has had all his current accounts permanently banned.

“His persistent tendency to engage in verbal abuse and insults, his lack of cordial demeanor, and his treatment of less-skilled players is unacceptable for any player, especially a high-profile professional player who has a regular opportunity to lead the community by example,” said Riot.

This is the ninth time Rivera’s behaviour has been assessed by the League of Legends tribunal – the game’s governing body.

“Today I was informed by Riot that I will be suspended for 1 year of the Season 3 Championship Series. Although the ruling is extremely tough, I agree with Riot that player sportsmanship is a serious matter, and I want to apologize to anyone that I’ve offended in-game and my fans,” Rivera wrote on a Reddit League of Legends community page.

“I fully understand that pro players are viewed as role models and should act accordingly. I’d like to thank my teammates and the whole Dignitas organization for the amazing year that I have spent with them and wish the team the best of luck going into season 3.

“Personally, I will not let this end my dreams of being a professional League of Legends player. During my suspension I intend to keep my mechanics in top form and remain a competitive jungler. After my suspension I hope to rejoin the championship series and once again compete at the highest level. League of Legends is my life, and I will do everything in my power to play as long as possible.”

Rivera’s harassment score had risen by more than 30 per cent since August, despite repeated warnings and punishments, said Riot.
