This gaming community solved online harassment. First they polled the community to determine local standards. Then they created a learning system which allowed users to penalize behavior outside community norms, or reward particularly good behavior. This is optimum because it allows each community to set and maintain its own standards. Parameters are created by the community and enforced within its own interactions, not devised and imposed from outside. This way, each little corner of cyberspace can establish its own ideals. Everybody wins!
