Ha! This should foil those nasty comment spammers. One of the unfortunate side effects of the growth of weblogs is the practice of comment spamming. Spammers, usually promoting Viagara or pr0n sites, place a non-sequiter comment on a weblog, with a link to a web site.
I just installed MT-Blacklist, a plug-in for Movable Type to foil all known spammers. If you don’t have it, get it. Ridiculously easy to install … if you read the instructions and follow them. I skimmed too fast and ran into hiccups. When I re-read the instructions a little more carefully (oh, set the permissions to 755? upload to what directory?), installation went lickety-split.
Spam slam, thank you ma’am!
