I know a couple people that were banned for cheating, they were kicking people out of lobby's for trials victories. Well, all he did was create another account and able to play in the crucible again a few minutes later. But that doesn't solve the problem of people who lagswitch during that game. I don't see how they can't have referee's spectate random matches and issue warnings/bans. I wonder if they even play the game from all the crap this beta game has been going through the last few weeks.
