yeah, we have the confirmation e-mail and graphical pin, but I've switched to various other registration confirmation libraries over the years.

I now just try to get in at least once a week and clean up the bots and add 'em to our banlists... hell, I've even changed the forum database and numbers to trick bots -- or at least limit them to a non-BB Code forum (hence this Welcome forum)... and to that extent, it's been pretty successful in preventing bots from posting links and images and coralling them for easy cleanup.
