In 2018, Facebook CEO Mark Zuckerberg announced that the company would appoint a content oversight board to act as the final decision maker when it comes to content moderation decisions. Like the U.S. Supreme Court, the board wouldn’t look at all decisions, but a small selection that rise to the top, perhaps

because they affect a great many people or because they are particularly thorny. Also, like the Supreme Court, the board’s decisions are meant to be final. Even Zuckerberg can’t override the board.
