Comment spam is back after a brief hiatus, and it's worse than ever. Not only is it approaching 300 a day, but a bunch (maybe as many as a dozen a day) are slipping through the spam filter and actually getting published. And so I'm disabling anonymous comments.
I really don't like this, because there are some of you who post here pretty regularly that way. I'll try leaving it shut for a week or so and then open it back up to see if that helps.
