I've been thinking about enabling comments on my Drupal-based blog (which is low traffic but has been around a long time). Until this point I had user-accounts disabled in order to prevent spam-bots from creating a lot of accounts. Several years ago I opened the flood gates and at one point there were as many as 30 accounts/day created by spam-bots. Even with captchas and Mollum spammers still seemed to find a way to sign up. I'm wondering what modules or processes group members are using on their site to combat the tide of spam. Cheers and thanks!

Honeypot
Give Honeypot a shot. The details of how it works are clever
Honeypot saved my site
Basically every site I build has honeypot now and the same tuning values work well every time (the defaults don't work 100% as the defaults are public information so writing a bot to get around it with defaults is trivial). It's basically the only spam filter I use these days (I hate captcha user experience.)
I'm not posting the values I use here as I'd prefer that they not be easily available for bot writers who use google but I'm happy to chat about it in a non-public medium.
flood control + captcha +
flood control + captcha + honeypot
has stopped nearly 100% of all spam account creations for me.
