So did I until I realized that robots don't have to follow redirects. That kinda took the fun out of it :( Except for one batch of Ukrainians who got so wigged out, it really did cut back on their visits.
Someone hereabouts suggested the alternative of redirecting back to the originating IP. Like Return To Sender. If it's a very stupid robot, it might even work.
