I should have learned my lesson two decades ago, that naive keyword-based censorship doesn’t work. A fair number of comments have gone into moderation recently as the result of my attempts to control long off-topic threads and other uncivil remarks. In think that in every case, I approved the comment.
So as of now, I have removed most of the moderation filtering. The only thing that remains is some cuss words and all the banned commenters. I have also relaxed the number of URL’s allowed to the point that no one should have a comment moderated for that reason.
