Battling comment spam

It’s a sad state of affairs when you come back to your blog after a week elsewhere and have to add another 56 domains to your blacklist. I’m actually getting more comment spam than legitimate comments now—this is becoming more than just a minor nuisance. I’m considering a number of improvements, including adding a moderation queue to comments on entries posted more than a month ago, disabling the comment form if the referral is a search engine (as per Russell Beattie’s suggestion) and adding some kind of wildcard support to the blacklist file.

I’d really rather not do any of this, but the problem looks like it’s going to escalate.
