I've been saying so for a while but today I finally got my act together and updated to Movable Type version 2.64, and installed the spam-thwarter plugin MT-Blacklist. No more comment spam. I'm happy.
Spammers have increasingly delighted themselves in spreading their comment spam excrement around my site, which I up until now have had to delete manually. Ironically enough, their primary spam-target is/was an old post about... weblog comment spam.
I went by Ryan's place earlier and ran into uncomfortable news which, well, are news to me anyway; spammers are exploiting a script, which comes with Movable Type by default, to send e-mail spam.
To avoid being used by spammers as a spam-sending droid, remove or rename mt-send-entry.cgi, you're probably not using it anyway so you could very well delete it. Read more about this in the MT forum.
