Idk but i am just guessing, didn't see the message anyone. When i try go into server just kicks me as soon as i go in and says Banned from this etc.
Tears linked you to the area where bans/unbans happen etc.
If it was your first offense on a official server I'm sure the ban was temporary and you'll be back playing tomorrow if you'd so choose.
In the meantime read the rules and you'll learn that intentional team kills and wounds are never permitted. Admins aren't all-seeing, it's very possible they heard someone attacking someone else only to turn around and see you kill them.
If you are being attacked by someone report them with 'i' chat, which sends a private message to admins on the server.
