Need a good WP Captcha

[Gerry]

I need a good WP Captcha to stop/prevent spamming of comments on sites.

Would appreciate recommendations.

I use http://www.google.com/recaptcha for my sites. They got a wordpress plugin as well > http://wordpress.org/extend/plugins/wp-recaptcha/

I've yet to find a captcha that blocks all spam on WP sites. I've going through right now and installing "bulletproof security" plugin on all of my sites, seems to work great.

SI CAPTCHA has always worked well for me. But I use it in conjunction with other anti-spam plugins, like http://wordpress.org/extend/plugins/stop-spammer-registrations-plugin/ . You can also use Akismet.

I like the math ones like this:

Keeps out the spammers, and the village idiots as well.
