Meta-moderation system

A meta-moderation system is an arrangement in some online forums in which users rate how good of a job the moderators do. The most famous site with such a feature is Slashdot.

In meta-moderation, a user can enter "Meta-moderation-mode" (or something similar) and will be shown a post that was moderated in its original form, and the nature of the moderation. The user then decides if the moderator acted fairly or not- and if not, in what respect the moderator was wrong.
