I am discussing this case with Zisko in PM. He sent me some chat logs, but as I said to him I have to talk to the other party and hear both sides.
As I suggested to Zisko, I will suggest you the same: please don't argue on the servers, admin has a right to warn you and then punish you. Reason for this is: Players get fed up, admin gets distracted. If you are unhappy with something post it on forum, but be sure that when you report someone your behaviour was not worst.
