Perceived continuing personal attacks, but I don't agree with the ban when dispute resolution is taking place. You're not being blatantly abusive, so I think this was probably a little over the top.
There is no ongoing dispute resolution - the ArbCom has reached a decision and he has been banned from editing! His continued spamming of this mailing list with accusations of childishness and bias against him has pushed the wikien-l (and IRC channel) admins too far.
