I keep getting spam registrations from KontupeR45842 and all kinds of other numeric combinations. Doing a G search I find 13k+ guestbook and forum membership spams. The guys using some kind of autofill program, and not the usual forum spamming software (that simply submits variables instead of actually requesting and submitting the form). Anyways, I banned all instances of his usernames using KontupeR* - figured anyone else with a forum or guestbook should do the same.
