First off, you CAN reread the rules, they're on our forums. It's under News/Updates and it's a sticky.
Second, we can only unban you via steam id. To find this, join a random multiplayer game and type "status" without the quotes in the developer console. To open the developer console, press ~ (Key next to the number 1). If that doesn't open the console, it means you don't have it enabled in the Options menu. GO enable it under advanced settings and it should work. Look for your name and then copy/paste the thing that looks something like this: STEAM_0:1:2453533
That's what a steam id looks like.
As for the ban, it was unsigned so either the Mod/Admin/Neek was in a hurry or you're lying. Glitched ammo is NOT a perma ban, no matter the seriousness. Sure it can be a 4 year ban, but it'll never be a perma ban.
I'll unban you after 2 hours if nobody else replies to this topic.
