Comment spam, which to date has been pretty minimal, has sharply spiked upwards the past few days. I suppose it's the price of increased site traffic, but it's annoying. Not that I get a lot of comments, but I definitely prefer to keep commenting on when possible. I have reluctantly decided to turn off comments on some of the more popular older posts (e.g. the ones on The Davinci Code and Fahrenheit 9/11) on my site for now, since they're the posts getting hardest hit with comment spam.
I'm planning on upgrading to Movable Type 3.1 when it comes out, in large part becasue it will integrate the MT-Blacklist plugin. If comment spam starts getting really bad I may implement the plugin sooner than that, but I'm going to try to hold out for just the one upgrade so I don't have to implement the same change twice.
