My good friend Michael A. Burstein pointed out last night that a comment he posted never showed up on the blog. That was strange. I took a quick glance at things and couldn’t find anything obvious. My spam filter hadn’t identified any false-positives. So I was going to chalk it up to a glitch. They happen. But this was Michael, and my mind just wouldn’t let go of it. So I dug further and finally decided to go look at the spam comments. There were 144 in the queue. And guess what, Michael’s comment was there, and I marked it as NOT SPAM at once.
But I decided to read through the rest, and it turns out I discovered 8 more comments that were flagged as spam that should not have been. Of these 7 were pingbacks. I marked all 8 as NOT SPAM and have approved them. That, plus a more careful monitoring of the spam folder should prevent this from happening again in the future. But if your comment was one of the 8, I apologize for this. It is very embarrassing, but I now believe I have the issue fixed.
