Banned for excessive teamkilling

The guy had been annoying and know-it-all to me and other people, and I really hate people who can't even say ni**er and say it as "n-word" (so the main reason for saying it was irony, not racism). The reason why I dislike those people is not something you would understand because of your mindset.
However the rules say I shouldn't be saying it and that should be enough for me not to, peronal opinion doesn't matter here.
I do understand that I was in the wrong and I shouldn't have said it. I'm not here to argue over the reason I was banned for. I just want to ask if you could please let me play on your server and I promise not to watch my words more carefully. Whether you ban me or not, you won't see me breaking the rules again. I got the mesage Immediatly after I was kicked from the server as soon as I said it, and that was already enough for me to regret my words and realise that I shouldn't be saying that. A permanent ban here is just, I feel like, a little overkill.

(If I even am permanently banned, but no one responded to my question, but I assume I am since it hase been more than a week and am still banned.)
