Mephisto Plugin: Inverse Captcha for Comments (anti-spam)

Absolutely no blog comment spam for five months and counting! Impossible?

No. It actually works.

Checkout this highly efficient anti-comment-spam trick and add an "outer floodgate" to Mephistos already very good spam-protection (Akismet).

This plugin easily extends your Mephisto blog with an "inverse captcha" mechanism which relies exclusively on CSS. No JS, no user action required. It even falls back/plays nice with non-CSS clients.

Here's the code:
