I've had 100% effectiveness with the "captcha" I added which simply asks the commenter to solve a rudimentary math equation. I went from about 30-40 spams a day to zero ever since. So far, nobody has complained and I am still getting real comments from people.
It does rely on Javascript, which puts a small percentage of readers in the "can't ever post" category, but the number of people not running JS in their browsers has become statistically insignificant, IMHO.
I like your "approval" concept, though, Jake. My goal was to eliminate any sort of maintenance, so I didn't go the route of needing manual attention to things. Yours makes for a more forgiving approach though.
