Ban Appeal

I was playing on Qwai River, I joined the PLA team, then I typed: "Ching chong pancit" in the chat. Then I went to the kitchen to get a glass of water, seconds later I was kicked. I attempted to join again and I got banned (It says here for excessive teamkilling, although the only teamkill I ever had was accidental in the past map which was Fallujah West.)

I read the rules and never ever does the phrase "Ching chong pancit" show discrimination to the Chinese people, I never committed racism in the server. I just want to be unbanned guys.

EDIT: Also my ingame name is Afr0.

Im curious, how do you accidently tk someone with the bayonet?
