"By taking certain moderation and voting statistics and applying a formula to them it should be possible to work out a ranking system that will show the quality of a moderator.
automoderations = 1 point accepted moderation (non-automod) = 10 points rejected moderation due to failed vote = -10 points moderations rejected for other reasons = -1 point deleted moderations = -5 points
Yes or No vote where user was one of the first three to vote = 1 point Yes of No vote where user was not one of the first three to vote = 0 points
This is not meant to be a definitive list, it's just an example of how a points systems could be integrated.
Note : The deleted moderations points loss is important because it will encourage people to think before they enter a moderation and will also mean that deleting a moderation that is about to be voted down will still incur a penalty."
