CAPTCHA is useless. Every single bot software is programmed to circumvent them. Recaptcha could work, but even then I bet that bots can get past it.

We just use Stop Forum Spam database, which runs a scan when a member signs up on CW.

I heard that reCAPCHA gets updated every 2 weeks  ;)

My main concern about Recaptcha though is when their server is down. On Omni we once used Recaptcha and had to get rid of it because everytime their server was down, nobody could register on the forums.

Make the answer to the verification thingy a word, eg. question would be "what's the coolest animal?" On 1bitforum, not a single bot has gotten through since we have that procedure in place, only some human spammers.

We try to keep our questions as simple as possible, though, so we had an hard time figuring out a good easy question that can't be misspelled easily.

Recaptcha is owned and hosted by google now, there shouldn't be any concern of it going down. :P

What if the NSA shuts down Google and Apple for refusing to decrypt their user info? :P

Street gave me permission to do another spambot purge. We went from 603 users to 471 in the process. 4 accounts among those 471 were approved, but require email activation, since they looked spammy, but had the same username as their email (which is sometimes an hint that it's legit). If they don't activate their account within next week or so then Street, aeTIos and Juju can probably delete them.

Why purging the Jedi's? D:

Also we blocked over 15K spammers so far (about 1400 slipped by and were flagged as spam or were detected later)

But Jedis aren't all that bad XD


Also when I deleted accounts I noticed that @Streetwalrus forgot to remove one bot account that actually advertised on the forums last year, then the same bot logged in again months later to spam again, and was never banned. That's the most lax intervention I have ever seen on a forum against a spambot O.O
