League of Legends' competition committee has dropped the smack down on a number of pro players due to Elo-Boosting. The company defines Elo-Boosting as "the repetitive and intentional act of an individual playing on someone else's account (a "client") for the purpose of artificially improving the client's Elo rating." Seven players and one coach, representing pro clubs that include Curse and compLexity, have had their accounts suspended for 14 days. Additionally, the cheaters have had their Season Two rewards revoked.
Riot also issued a "first and final" warning to Good Game University general manager Sam "Hexo" Bouchard for allegedly using a DDoS (distributed denial-of-service) attack to disrupt an opponent's internet connectivity. The LoL competition committee provides an example of Bouchard's antics and it also notes that he currently boasts the worst harrassment rating among all LCS North American players.
