they leave a chat function on if one is not participating in the actual game. I find it both amazing and equally annoying when trolls come into the room asking for money or just being obnoxious.
I really have no tolerance for that as you may have noticed on Wednesday nights when they come in asking for money.
Can't remember who but it might have been Annie Duke? who said that when she plays online she has all kinds of creeps in there being rude and downright disgusting.
I am really surprised that some sites allow this.
