Overactive Spam Filter

I want to apologize on behalf of the so-called "spam filter" that blogger has installed and that I can find no way to disable. It has been overactive recently--and since I have been busy grading, I've forgotten to check it's work. This morning it suddenly occured to me to look at what was in the spam box--and I found that a dozen legitimate comments had been directed there instead of being posted (whereas NOTHING that qualified as actual spam was there). There was too much, scattered over too many posts, for me to go back and check for each misdirected comment whether the commenter had finally succeeded in getting a version of the comment up. I did find a few such cases, which are hopefully now posted. And I prioritized posts from newer participants simply because the spam filter is supposed to "learn" from its mistakes--if it's been told before (by me) that you're not a spammer, it's less likely to treat your comment as spam in the future (but still will do so occasionally for inexplicable reasons).
