Spam checker failure

Something went weird with the comment anti-spam system I use and it purged all of the non-spam comments published since 10/20. This does include all of the very nice comments I had on the last post, Guaranteed Delivery of Email, which was all about spam. Rar! It was one of my most-commented-on posts, too.

Happily for me, I saw the strange state it was in before the comments got lost, so if something similar happens again I should be able to file a bug-report. Very sorry about that.
