Hi Russian,
The ban was specifically for Kill Aura. There was some suspicious mining, but I'm going to give you the benefit of the doubt and assume you weren't xraying. As for what you were banned for, it wasn't for what you were doing immediately prior to being banned. It was a bit prior. We clearly saw you doing immediate 360 turns and attacking anything that came near you. It was unquestionably Kill Aura.
That said, I do want to be nice to you. You've been a great player and never been warned or in trouble for anything, and I know everyone makes mistakes at some point. With that in mind, are you absolutely certain you were not using it?
