Ban Appeal for Disgusting Beggar

I was playing Lashkar Valley INS today and was banned for "excessive teamkilling" despite not teamkilling anyone the entire round. This ban was without warning and I didn't see anyone report me for anything either.

My in-game name is "Disgusting Beggar", and this ban occurred around 45 minutes or an hour ago.

The ban may be temp (unsure how long "temp" is) but I figured I'd post here anyways as a false ban is a false ban.

EDIT: Ban appears to be permanent given more than 3 hours have passed (and a server crash + multiple map rotations) and I'm still banned.

I use global chat so much because we were doing map suggestions and it was being used by others for non-important uses. As for the rest, yeah, I was being an asshat and I apologize. I'll keep global chat to map suggestions only in the future.

Still, I disagree that this should be a permanent ban, especially given I wasn't intentionally trolling and this is (typically) the only populated US server that I can play on. And I know warnings aren't given, but it seems a bit harsh to permanently ban without warning given I (to my memory) haven't been kicked/banned before.

Could this ban be taken off/reduced to a temp. ban?

Slang I used, to be used like kufar/infidel? Heard it earlier on comms and found it funny so I used it. Essentially a more offensive version of amerifats.

(I am American and don't (actually) have anything against Americans. I just like to joke about it.)
