That fact that you need to be prompted to apologise speaks for it's self...
You say you were banned for bad attitude because you were defending yourself... You wouldn't have to defend yourself against any OSF member in that way because we play for fun, we don't flame for the hell of it and we punish people that are disrespectful to ourself's and other on our servers.
Come back and ask to be unbanned when you have understood what everyone is saying to you and you have matured.
