    Bots can't. Humans can. This is all about stopping bots. Not humans. It isn't possible to stop humans to create spam accounts.

    Yeah exactly. Do you think they can figure out ones like "whats this website called?"?

    Not that I have an ingenious alternative, unfortunately.
    Oh, well you don't have to use mathematical questions. Just like in Steve's link, you can ask for spelling or simple YES, NO answers.

    I currently run a phpBB with an additional Spam Protection since I was getting flooded with Spam. Now there's a system in place that will ask simple questions. For example: 4 + 3 is? ... Yeah! 7. Since you can add your very own custom questions and answers, this successfully keeps spam bots from registering. I would like to see something like this built into vBulletin.

    I've been quite happy with the Prevent Spam Post mod. So far it has captured every spam posting attempt without any false positives.

If you're site uses a custom font list and custom background images then it would be like salting your MD5 hashes to break rainbow tables. With vBulletin you could easily change the fonts and backgrounds used on a regular basis as well. Just build several sets and switch them out every month or so. The humans won't notice the difference but it would take ages for a machine to get a captcha that has been decoded and recognizes.

    I've never seen any proof of that.

    I dunno if you can call the phpBB2 a CAPTCHA dude, at least the on in the BB3 stops bot, the one in BB2 stops nothing at all, the one in vB is far much advanced and hardly breakable + NoSpam plugin found on vbulletin.org, it just stops all.

    Just keep in mind that no registration verification can stop a human from filling out the form, then releasing the bots afterwards. Like with any security, if the bad guys want in, they will get in. And that's the limitations of technology and being public with it -- so no matter who or what it is, spam will exist as long as humans want to spam it.
