I haven't been on MW2 an awful lot, yet I've heard him get outright aggressive and being a real asshole towards other players countless times. Not insulting playfully like most other players do (even though we do have a number of real toxic sobs on there), but the real deal. Still don't understand why this kind of behavior isn't kept in check. Anyway, it doesn't look like anything is going to be done about that anytime soon, so if it gets too much Gothic, I can only suggest that you jump in in FT1, where people actually respect each other, with very little of that kind of bullshit to deal with.
