This is the biggest problem with the death of arcade gaming and networked console gaming, it's successor. With anonymity and such a huge scale of unfamiliar people, it really hampers the camaraderie of playing with people face-to-face. 10 years ago, if someone played Street Fighter with you and called you a #!$ !%!#@!, you'd be sure, that you (or your friend) would probably smack the shit out of them right there. With no threat of recompense, there is nothing stopping people from being d-bags.
