Although I didn't hear the taunt and I wasn't in the game when this happened, I was actually with you and Anon on Teamspeak. He clearly told you to not do it again and you - apparently - did. You should also know that we don't take kindly to earrape taunts.

As a small sidenote, I'd still advice you to apply even if this doesn't get appealed. If you don't break anymore rules then you still have a chance of getting accepted.

Good luck.
