Every four weeks, Reddit will publish a list of how much karma each user earned in the community during that period, as a proposed score of their contribution. After this, the community has 1 week to review the list and propose any changes, if it wants.
To propose a change, publish an alternative list and create a poll to have the community approve it. If the poll meets the minimum quorum and passes (by Points), it becomes the official contribution score (except in case of significant bribery). In case of multiple polls passing, the one with the most Points cast in favor is used as the official result.
