Just an admin post for today - for the time being, I've turned Comment Moderation on for all posts. I'd usually let the most recent ones have free comments so conversations could happen while I was away.
However, I've been getting a lot of spam comments - more than regular comments in some cases. For at least a short time, I'll have to moderate all of the comments. I'll try to poke in multiple times a day for a few days before I experiment with turning moderation back to the previous regime.
Sorry to have to do this, but spam is spam.
