Our great spam savior Jay Allen has just released version 1.5 of his excellent program MT-Blacklist, and it features a new ability to clean up spam that’s already appeared in your commenting system. I’ve been doing great ever since installing the last version (after the deluge of spam comments I was the target of, which was also killing my Mail progam with all the notification messages I was getting). Definitely a must-install for all you bloggers out there who use the Movable Type software to power your blogs.
