4chan seems to have a superior system wherein there are a small number of mods who take recommendations from a large, churning group of janitors. These janitors can only suggest bans and must follow a template for each of their ban recommendations. However, the janitors can delete posts/images at will (reversible by mods). Thus, the system is both evenly-applied (most of the time) and highly scalable.
