most of the time its just forumers gossiping over other forumers thinking that it can't and won't hurt anyone just because its not on the forum. It takes a lot for me to recognize a random person on the internet a friend, and so far most of the groups seem stupid and all they talk about is "lol randum lolxD" stuff that's not even interesting. Then you've got that one kid who has like, an earthquake in his damn mic.
I have to agree with kigshal on the fact that I've seen Skype groups or even steam chats turn to stuff.
