Apologies to anyone who posted a comment last night or this morning and didn’t see it appear. This was due to my having turned up the discriminator on the all-but-worthless Movable Type spam controls. Instead of blocking spammers, it wound up attacking legit commenters. My bad. Every day I spend at least 30 to 40 minutes (maybe closer to an hour) banning this and that spammer and deleting their posts. Still trying to figure out the right plug-in to use.
