ip/user banning Emergency?

You can also ban IP's directly via apache/.htaccess.

As a side note, you do realize just how rude you're being when people keep offering you help and you respond that you're looking for "good coders" instead of the many solutions already presented to you, right? There is no big red button that you can just push to solve all of your problems. You're going to have to learn to run vBulletin and your webserver, period. I normally wouldn't say anything like this but the last time I helped you, you did the same thing.
