Hi,
I am supporting a blog right now and ran into the same issue. Akismet was running for a while, and the owner opened up old articles for comments, which increased the monthly SPAM load from about 500 to 11000 and counting. I found your plugin and thought it is just what we need. I tested it manually, and it works, but as the OP said, the posts marked as spam show up in the moderation queue with a note “flagged as spam by Akismet”, even though I have configured it to trash the spam if the CAPTCHA is not solved correctly. The site is positiveparentingconnection.net. Any ideas? I can provide screen shots if that helps.No other comment-related plugins are installed.
UPDATE: Thanks for your test, just saw your test comment in the rash, where it was supposed to go. I think I found the error – in Settings/Discussion, there was a sitting to put any comment with 2 or more links into the moderation queue. Might this override the trash setting in your plugin? I turned it off now, waiting for the next SPAM bot to come by. Curiously, I wonder how the spam bots seem to get by reCAPTCHA.
