I wish Movable Type had something better than Akismet which does a pretty good job filtering spam but still very quickly populates Movable Type’s junk folder. While this keeps junk comments from ever appearing on your blog, it still takes time to sift through them in order to locate any good comments which end up in there (which has happened). I have heard they have CAPTCHA support in version 4.0, however we are still running 3.2 and have not gotten around to upgrading yet. My thinking is that someone somewhere must have developed a plug-in that would allow me to install CAPTCHA or a comment challenge of some sort in the version I have right now. I can’t imagine everyone who uses Movable Type spending their valuable time sifting through junk comments to make sure that good comments are not accidentally deleted.
So late last night, with a little searching, I found an awesome plug-in developed by Jay Allen simply called Comment Challenge plugin.
