I don't think "I killed a lot of bad guys" is really a good reason. You're going to need to elaborate more.

Keep in mind if you consider "bad guys" as bad teammates, and you were banned for teamkilling, this is a timed ban, and will not be lifted until the time expires on it.

So can you please elaborate? Also, were there any SmG members in the server at the time that you were in? What server were you using?
