They are all steam, this is the same situation you had when you swore blind it's not your fault the bans aren't working and should be unbanned and you WERE.
The bans aren't working, you know it, i know it, every admin knows the short time bans aren't working. It was a misunderstanding, they don't know the bans aren't working in the same way you DID know. They shouldn't be permanently banned for that.. If you amx_ban and they don't get banned and no one informs them that they are banned for 60 minutes then how should they know that they were banevading?
