Google Vs. Blog Comment SPAM

Via the Ruby general list I stumbled on Preventing Comment Spam from Google. This seems like an easy enough idea; I will have to see if I can scrounge up enough time to hack it into WordPress.

On a related note, I heard that sometimes spammers actually have real people entering these inane blog comments. If so, I think they need some more training. 😉 It seems they are leaving obtuse comments without a url linked, and therefore with no purpose at all?!?
