You'd just need enough traffic to teach a tool like PWNtcha, and that's
only necessary for unique CAPTCHAs. Existing libraries are probably
already covered.

Employing a CAPTCHA raises the bar, but there are less annoying ways to
do that. Can you tell I'm not a fan? :-)

Before anyone notes my hypocrisy, my blog requires people to indicate my
first name in order to post a comment, and although I might adopt a
better approach, at least this approach is accessible.
