there are a few ways to counter-attack this ...
- turn off all comments
- turn off comments for people without accounts
- put a set of radio buttons on the same HTML form with the comment box, with the default button being "I am a comment spam bot, do not post this comment"
- require the poster to type a randomly generated word which is displayed in a gif file, with some distortion thrown in to screw up OCR.
The trade offs are how open do you want to be, and how high do you want the barrier against bots that abuse that openness.
I'll volunteer my feeble PHP skills if that would be helpful.
