I saw you teamhitting multiple people in the spawn then disconnecting. No matter the offense of the other person you should contact an admin, and let them kick or ban the offender in question, if not just take screenshots and make a ban request. It is the work of minutes.
You are by no means a new player, and you must certainly know the rules by now, if you had handled this properly he would have been looking at a few days ban, and you would be in the clear. But as it is, you are scheduled to be unbanned at 29.03.2012 17:29:00.
