I was banned yesterday afternoon for griefing another player. I realize that this is against the rules. In my case, I was griefing a friend of mine. On skype, he was said jokingly "heh heh I wonder how long it'll take for them to ban you if I say you did this" He made some silly comment on the chat that would have authorities looking at the situation. If you were to ask my friend who I was griefing if he found my prank ban worthy, he'd [uberratchet] would say no.
