So - just tossed in this plugin, and it almost works. It blocks all comment entries that fail, and allows the ones with the right answer. GOOD.
What it does NOT do on my blog(s) however, is flag the comments as SPAM - it just sends them into never-land. They don't get logged into the DB at all... BAD
Coupled with this, the error message posted on the comments page is the one I entered in the "Incorrect response entered:" regardless of whether I entered a response or not. WEIRD
Thoughts?
