Combating SPAM on forum

[occalifornia]

Can we institute some sort of registration confirmation process for new accounts on these forums so as to reduce the incidents of accounts posting spam?

admins, please chime in!

I think it would be best to use those flash captchas with puzzles where you have to complete a picture or something. Bots can use Google Recaptcha solving API's like Decaptcher on popular forums like mybb easily.
