Get enough people together, there's going to be some you don't get along with. As has been mentioned: thicker skin, .squelch, .report if they're being abusive and that bothers you, don't talk crap if you can't handle it being dished back.
With as small as this game is, it does tend to make it more personal because you tend to see the same names more often.
Heh- small anecdote. The latest COD had a free weekend a couple weeks ago. I'd never played any of those games, thought I'd give it a go. In a lot of places, COD type games are held up as a sterling example of community toxicity.
In the entire weekend, out of the maybe couple hundred people I played with, I saw one person I'd label as "toxic". The rest just shut up and killed each other.
That Sunday night, I logged into here and in the space of ten minutes saw about a half dozen people slinging mud of some kind on 200. That really shocked me.
