He was banned, me and him have both been on a very high warning level since the old shoutbox was closed because we had a fight publically. We can honestly only speculate so it could have been anything, voice recordings he was posting targetted at another member, certain things he's said in posts. We can't know for certain because I think that one or two "small" rule breaks might have been enough to bump the warning up to 100% and that is an automatic ban from what I'm aware.
Master said that he would be able to appeal it so it's up to how he approaches it now. Hope that helps.
