I kicked / banned you for intentional team killing. I know its frustrating when you get team killed and especially when they are obviously griefing, but the answer is never to TK back. I was playing the game as well as trying to admin, so a response is not always immediate and I may need to observe before kicking and banning.
I also banned the guy you were referring to for his multiple TK's.
I will give you the benefit of the doubt and reverse the ban, but please just report it next time and give me a chance to observe and respond.
