Why are there so many crazy, foul-mouthed, ill-tempered posers in Yahoo Games pool game/chat rooms?

So many people in yahoo games rooms, specially pool rooms are just simply crazy, rude and quite simply bad! They do anything to get points, are sore when they lose and behave so poorly in general. Some are regulars in certain rooms and hang around just simply to find some poor guy to fight or put down. Language is foul, racism is rampant, attitudes are bad, basic decency is nowhere to be found. Why? It is one baffling phenomenon where people who otherwise are normal become animals in these game rooms. Posers, because so many pose as people they are surely definitely not, like star athletes, millionaires, 6 foot five adonises! Been visiting these rooms to play regularly and have been witnessing this for years now.
