Just to throw in my own experience. I cannot count how many times I saw people ostracized from the server community for being a douche. Or ninja. Or what have you. During the time before LFD. I STILL remember some of their names. Now I go into a group and roll on what I want. Do what I want. Afk as much as I want. Why? I'm not actively making an effort to be an ass, but it's just so easy when I'm not going to see any of those people ever again.
