I noticed Fr. Z's problems with this item too: "The software that scans for spam has become more restrictive. Sometimes it will pull completely innocent comments into the queue. Sorry."
Recently I visited the "SPAM" tab under the "Comments" heading in my blog editor, and I was dismayed to find that nearly two-thirds of the comment pulled off into that queue were not spam but perfectly legitimate. I have not idea why they were flagged as spam.
In any case, I've tried to restore as many of these as I could find, if belatedly. My apologies to anyone who might have thought I simply filed his comments unceremoniously in the trash bin. I didn't. I will keep closer tabs on that proverbial round file.
