That's a really good question.
Our content review teams are always looking at content decisions and making sure our policies are fair and are enforced fairly.
We also recently set up something called the Oversight Board, a really interesting model that examines the decisions we make around content. If we make decisions to remove content or to leave content up that our users disagree with, they can appeal those decisions to the independent Oversight Board. The Oversight Board will take a second look at our decisions.
