Banned for... Being racist? Options

[Fliedel]

Hello, admins.

At first, sorry to bother you with a subject that seems way too recurring in this forum.
I used to play a lot on both of your chivalry servers. Used. But somehow, I got permanently banned:

This evening, as I was defending king Argon in the Limited archers server, I got kicked from the server, for saying "racist language". I am quite disturbed because I didn't speak a lot in the chat, and I nor anyone else as I could see has said something that could have been seen as racist.
I maybe said something rude to a fellow gamer, when he asked something like: "Why did I got thrown in The Agatha noob team?" as I answered upset (as a member of the Agatha team), and kind of mocking: "Because F*** you! That's why!" (without censoring the sentence).
I agree that we could take it badly, but I didn't mean being agressive, and there was no racist content.

Would you please unban me? As return, I'll promise not saying any rude words in the chat (My ingame tag is the same as my account).

Good evening, and sorry for eventual misspellings, English is not my native language.
