Jay Allen has released version 1.5 of his esteemed comment spam eradicator, MT-Blacklist, which works on Movable Type. When zipped, this little bundle of happiness is only 32kb.
I just upgraded my version in, like 1 minute. *Yawn* Can it get any easier than this? Never mind what Wired omitted to say. We'll say it: The man's a genius. Three cheers for Jay!
