I've finally gotten sick of smacking down spamroaches. WP-Spam-Free is still doing a decent job, but it's letting enough crap through that it's overly annoying - for me, in despamming the site, and for people who have subscribed to comments by email or RSS because they get spammed. I've just re-enabled Akismet, and will be running it alongside WP-Spam-Free for awhile to see if they can double up and plug the holes…
