I'm guessing it's a type of outsourced job. Where someone just provides the list of forums where they registered.
In such cases, most of the time they use the same user id on all boards.
So it's easy to use Google api to run a search on each new registered user. Check the number of estimated results. And if there are a lot of results, just flag them for a possible lock. Or just lock them after a manual review of the search results.
Of course, there are plenty of names like "Mike" or "Jane" that would have serps with a great number of results.
But most of the time, you'll have a clear indication.
Here is one example that just flagged on my board: corpobb
Anyway, if you have a problem with "sleepers" registering in great numbers, you might want to try this approach. It's not hard to automate and get e-mail notifications with links to serps pages for all suspicious new accounts.
I know phpBB has eliminated the bots at this point as the image captcha has not been broken and there are already plans on how to step it up when it is.
That really leaves humans, I'd look to the forum software for solutions whether they are built in solutions or mods. phpBB for example has a new feature as of 3.0.3 that will kick the first X posts to the moderation queue for new members for review by a moderator before it gets posted.
the remaining part of the registration is sent to that email address
That's an interesting idea, I'm assuming by that you're not referring to the activation email and you're sending them a form to complete in the email? If the user has HTML disabled?
The image captcha in phpbb has worked so well I've disabled email activation myself. It's only a speed bump for human spammers....
<input type="text" style="visibility:hidden" name="email" value="">
(or use a CSS class with visibility:hidden set)
Then in the registration script you check if the email field is set. If it is, you ban that user. Of course you need a separate field for the real email.
