Understandable, he is well known to use !ztele from zombies. But for future references, we never base votes or opionated votes without visual support. It's recommended to watch the demo, and then vote.
For example, in this case, 1000ticks before, he !ztele'd but not from a zombie. I thought that was the ztele and was going to vote unban. But viewing the demo more, he did !ztele from jimmay later on.
