Seriously, that is not at all the intended purpose of bugmenot. Remember, for it to provide usernames to the masses, someone would have had to sign up for your system and then post the username/password pair to bugmenot. The same could be done by posting the username/password on any forum, if perhaps a bit less conveniently.

Unless your guestbook is a really happening place - and I mean in a big scale - I do think it's odd you're being targeted from bugmenot. I'd suspect one or a couple nuts. Time to scan your logs for anything in common among the abused signups.
