Peer-to-Peer Accountability Enforcement/mechanism/CW

Credibility Weighting (CW) means that all ratings do not figure equally in the aggregate. A rating from a user with a high credibility rating will count more than a user with a low credibility rating.

A pitfall to avoid: Although it would seem logically consistent, users with negative credibility ratings must not have negative influence on the aggregate, as this would give them just as much power to "game the system" by voting against accounts they actually want to boost. Weighting should either bottom out at zero, or else should follow some curve that never quite goes negative (e.g. log() of the user's rating).
