Antiban isnt an actual "Anti Baning" magical software, i believe opcode set that name just to show you guys that he can't be banned by the anti cheat, most of the servers you'll trick it, this isn't new and has been ages outside since all you need is to set up some m0d_Sa patches and rejoin the server, that's all what it does. You still can get banned by the admins.
Sometimes i can't believe some people are clueless lol, you will never find a fuction that actually prevents you from getting banned by the server or by the admins.
