Being generally annoying+posting under multiple monikers=typically permabanned
I made the mistake of trying to change my own name by just starting another account once, and got banned. Luckily for me I was in regular contact with one of the most famous of AH members and he was able to explain the situation to the moderators/administrators. Unfortunately for me I was a posting fiend (as I still am), adding to the suspicion.
Thanks Sheep, I still owe you man.
