The trickle of comment spam that I’ve been seeing in my comments has finally increased to the point where I was finally driven to install MT-Blacklist, and I have to say I’m amazingly impressed with how easy it was to install, and how clean the interface is. Imported the current blacklist without any problems, and it even found a stray comment that I hadn’t realized was spam (it was trying to give me some line about how my site didn’t work in OSX; nice try, sister!).
