I just realized that TypePad, which hosts this blog, has been over-zealously filtering some legitimate comments as spam. I just added a comment to a recent post (the subject of most of the rejected comments) explaining the problem.
Amazingly, my own comment about the over-zealous spam filter was rejected as spam! That's what happens when rigid dogma, in this case programming related, overrides common sense.
Hopefully TypePad will get its act together soon. Until then, I'll check regularly to see if any legitimate comments have been flagged as spam and publish them if they have been. Here's what I said in the comment:
Regarding the "censoring" of comments, I didn't have anything to do with this. It was TypePad's fault, the service that hosts this blog, as explained here.
TypePad recently made its spam check more aggressive. Overly so, obviously.
I'd rarely gotten spam comments after requiring the verification check where you have to type in some letters to verify that you aren't a spam "robot."
So it never dawned on me that genuine comments might be getting filtered until I read a notice from TypePad recently.
Anyway, I found eight comments in a "spam" section and published them. I believe most were related to this post -- forgot to check this more closely before moving them to the "active" category.
I apologize, on behalf of TypePad, for any confusion this has caused. Again, it wasn't me censoring the comments.
