Well for one, people yelling at you because you killed them or something, I mean good God, I hate those types of people, I mean sure dying in a game sucks and its sucks even harder to wait for your character to re spawn, but that's how it is, you played with people around the world, what do you expect? Also those people calling you names just because they killed you in the game, those guys are the worst, oh, and also annoying 13 year old kids.
