Meta-moderation system

A meta-moderation system is a system in which moderators are rated by users. It is commonly used to prevent abuses of a moderation system. Meta-moderation is most frequently used in internet forums, blogs, and user-driven news sites.

Two examples of sites with meta-moderation are Slashdot and Kuro5hin. Meta-moderators rank moderations as "fair" or "unfair", generally without being able to see the author or moderator of the originial post. The practice is designed to curb "improper" moderations, or moderations that go against what the community at large considers acceptable. Generally, a moderator who receives too many negative meta-moderations loses their moderating opportunities or privileges.
