With MovableType 3.2b4 (actually in an earlier nightly beta), SpamLookup is bundled in and makes use of the "feedback scoring" system to "junk" spamments. Thus far, the results are astounding: I've had one false negative and one false positive on top of about 11,000 spamments.

Those are impressive results, and the darn thing (so far as I can tell) isn't even using a Bayesian filter. It's just determining which comments are spamments and which are not by looking at the message content (for URLs) and cross-checking that with DNS entries and lists along with some small word lists. Judi is similarly impressed.

Is this all it took? I'm still using MT-Blacklist over at The Sand Trap, but only because I'm waiting for 3.2 to be finalized before I install it there.
