a more surgical approach
My suggestion for a more surgical approach -- for the interim at least -- would be for anonymous monk posts to only show up to those over (say) level 20 until they have been approved. That same group would be to consider them for reaping.
Since only those over the chosen level will be able to see them, only they can approve them, but there should be sufficient people around at most times to ensure the good stuff don't wait too long for approval.
Anonymous flames and trolls would be invisible when posted -- thereby removing any positive re-enforcement -- and disappear without trace if offensive.
Good AM posts get through as desired.
