You were a serf, correct? Regardless, he broke the rules and will be banned.
I find it most humorous that people think they can break rules while admins are offline, because the punishment for breaking rules when no admins are online is actually much more severe than when you break rules when admins ARE online. If he did this while an admin was online he only would have received a kick, however since no one was he gets a ban. Let that be a warning to all who seek to break rules in the future - just because there are no admins online does not mean you can get away with ****.
