Jon Cogburn (LSU) has run a little experiment. For months he and others have been unable to comment at Daily Nous. Long thought to be the result of my tyrannical and heavy-handed moderation, this problem has now been traced by Cogburn to Askimet, a spam-filtering service used by many blogs, including DN. Apparently, in some cases, having one of your comments marked as spam at one site that uses Askimet can result in your comments being automatically withheld at other sites that use Askimet. If this happens, your comments will just not show up at all—not even in the spam folder. What to do? Cogburn figured it out (his comments now show up) and he tells you, right here (updated link). Thanks, Jon!
Guess I’ll just have to start blocking his comments manually.
