MiceChat uses a system of reputation as a form of self-moderation. Members can give positive reputation to another member if they feel that member has made a positive contribution to the board. Members can also give negative reputation, which subtracts from positive reputation, if they feel someone has gone out of line or posted something mean-spirited or inappropriate.
The amount of reputation a member can give depends upon several factors, including, the amount of reputation they have, the amount of time they have been registered with the board and the amount of posts they have made. The reputation a member can give is called their "Reputation Power Points", and is usually about 1% of their total reputation. The amount of negative reputation a member can give is about half of their reputation power points.
Members are limited in the number of times they give out reputation in a 24-hour period, and must give out reputation to several people before giving it to the same person twice.
All members start off with 10 reputation points. And reputation given by new members remains null until they have made 20 posts.
If a member's reputation falls below 0, they are only allowed to post in the Litter Box, which is separate from the rest of the board, until they receive enough positive rep that their reputation totals above zero and they can post regularly again. If a member's reputation falls below -500 they are automatically banned from the boards.
