And this is why it's best to err on the safe side and avoid intentionally teamkilling altogether.
I understand you were frustrated and had I noticed the TK following yours, I'd have addressed it in the thread, but the ban logs are massive walls of text.
It really helps to have it addressed to us so we know what to look for.
You have no ban history other than this and have been a good player, so I don't expect this will come back to haunt you, but as I've said before, if someone complains, I'm obligated to do something.
Fuck that, I assume everyone loves me and I end of round tk randoms semi-frequently (well not that often actually because I'm usually never alive at end of round). It's a one hour ban, go outside or wrestle yourself for an hour.
