I think that depends on the value of the service that they're blocking.
I have a trivially breakable CAPTCHA on my web blog, but it cut automated contact form/reply spam down from dozens per day to zero.
They definitely have a place, just not for anything super high value.
- pilom 15y agoI feel in that case, a honeypot field is a better technique. It has approximately the same spam-rejection rate and doesn't hinder your real human users.
- alttag 15y agoBad behavior and Akismet combine to do the same thing (WP). The trouble is, you've made life more difficult for your users. On blogs, non-image "CAPTCHAs" are trivial. (e.g., "Put 42 in this box -->"), so long as your site is low enough traffic that no one cares to write a bot targeting you.
