I feel somewhat compelled to defend EVE here. While it's true that those people do exist (as they do in any community), I would say by and large the majority of people who take on a 'cut throat' persona are keeping that persona only within the game. I've heard time and again about people who blow up other people's ships for fun finding out that the person they just blew up was someone who had only just started playing, and would send them some money and a nice note. Or when something awful happens to a person in real life, the community will offer their condolences. There's even a well-known in-game chat channel that is dedicated to helping people who are depressed and having suicidal thoughts.

So yes, the bully scammers exist, but I think that compared to any other MMO, a greater percentage of the community actually cares about others.

Doesn't change the fact that they will blow your ship up given half a chance though :P
