The vast majority of spam messages that I've deleted from this board appear to have been generated by a bot. So it's either A. posted by a bot, or B. generated by a bot and copy-pasted into the forum by a human.

It would be the other way arround I guess ? Created by humans, posted by a bot. How could a computer create a message by it's own, and then an human stupidly copy/paste the message ?

First, a human constructs a template and a list of interchangeable parts (for example "bump this thread!" vs. "kick then ban as soon as possible", or random selections from Project Gutenberg etexts). Later, the computer fills the template with pseudorandomly chosen parts, and either the computer posts it or a human copy-pastes it.

I found another canary in the list of new members that haven't posted yet: Google the user name and the part of the e-mail address before the @. If either shows up as a banned spammer on a couple other forums, scrub the account.

I also increased the delay after post from 5 seconds to 30.

Thanks for the suggestion on how to purge spammers' sleeper accounts. It appears the spam rate has declined sharply (to 0 it appears) now that I'm doing this.

Out of curiosity, did the rate of new spammers drop any after Memblers modified the registration page?
