Moderation is labor, and you get what you pay for. Given how notoriously mental health threatening Facebook moderation has turned out to be, adding unpaid moderators with no health care benefits and especially no mental health protections seems the exact wrong direction for Facebook.

That said, I absolutely agree that the answer is likely one of checks/balances/as much transparency to the adjudication process as possible, and yes Facebook has a lot to learn there from existing governmental technology.
