Fortunately, or unfortunately, a glitch in how it works with article comments means that it just prevents them from saving, and doesn't explain why. The comment submits like it usually does, but it doesn't appear on the list. That way, people won't know how to get around them. At the same time, it logs what they were going to do, so we can check what the filters actually block.
