I’ve been using “Jay Allen’s Moveable Type Blacklist”:http://www.jayallen.org/projects/mt-blacklist/ plugin for awhile now but I have yet to see it actually stop a comment spam until now.
Two spams from two different IP addresses were stopped within an hour of each other yesterday with the help of the plugin. Unfortunately another one did get through but I deleted that post within a minute of it being added and then sent the offending domain to the “Spam Clearinghouse”:http://www.jayallen.org/comment_spam/ for addition into the blacklist.
Thanks for the awesome plugin Jay, I can honestly say it really works
