... As I told you in the PM, addip is an HL command. If something is broken with it, talk to Valve. So either deal with the problem, ban by SteamID, or get another ban plugin.
As for this thread, locking due to it not being a Scripting question.
I do not browse the forums regularly anymore. If you need me for anything (asking questions or anything else), then PM me (be descriptive in your PM, message containing only a link to a thread will be ignored).
