Jay Allen's MT Blacklist is the greatest Moveable Type plug in ever. If you don't know what I'm talking about, well, basically Weblog Comments have been rendered practically useless because of spammers who program robots to visit weblogs and leave notes that say thing like:
"Hey, great site! By the way, wouldn't you like a larger Penis? Just click here!"
The Spammers engineered a sneak attack, but Jay Allen has issued a phenomenal counter attack. It appears comments spam has had its 15 minutes of fame... for now.

Oh yeah, that means comments are back! (not that I ever got too many)
