Ever noticed how all the bots look for signup.php or wp-signup.php
even though the files don't exist in a normal vBulletin forum.

How about linking them to a rick-roll.php script?

so adding this to the /.htaccess file worked good enough

RewriteEngine on
Redirect /wp-signup.php http://www.youtube.com/watch?v=oHg5SJYRHA0
Redirect /signup.php http://www.youtube.com/watch?v=oHg5SJYRHA0
