Bad behavior from Bad Behavior
Shows how often I update my blog here.
Turns out that, because of a glitch in the “Bad Behavior” plugin that I have installed here to counteract spambots, everyone was being prevented from commenting.
And because I post so little, I didn’t learn of this bug until 20 days after it was discovered, when I tried to post and was blocked from doing so.
So anyway, sorry for anyone who’s tried to leave a legitimate comment here during that time… I’ve upgraded to the latest version of the plugin, so only actual spammers should be identified as such now.
