After the Flood: Captchas.
Also, since I came back to find over 10,000 spam comments plastered all over the Ghost, I've decided to take drastic action and installed a Captcha system, in the form of Jay Allen's comment challenge. So, if any of y'all want to leave a comment from now herein, you'll need to answer the not-very-tricky "challenge question." (The answer, as the hint basically tells you, is Berkeley.) As a result, the spam ratio around here has gone from 10-15 a minute to none, zip, zero over the past 24 hours. Can the war on spam finally be over? I'm not rolling out the Mission Accomplished banner just yet, but I'm cautiously optimistic.

I was going to suggest you look into reCAPTCHA and do a good deed while fighting comment spam.
Great question! I really like the hint. :)
Since I implemented a similar system at my site a few months ago, I've had ZERO comment spam. I figured I'd have had to change it by now. I can't believe something so simple works so well.
reCaptcha does seem pretty cool. For now, I'll probably stick with this system, particularly if, as Kris says, it actually remains spamproof. That's ten minutes a day I can now do something else with...woot.
