Two years after CEO Mark Zuckerberg first mentioned its creation, Facebook on Wednesday unveiled the initial 20 members of its new “oversight board”; the board will effectively act as Facebook’s supreme court, ruling on what content is and isn’t allowed to remain posted on its platform. The board will have the final word on all things related to Facebook’s content moderation policies and, according to Zuckerberg, will be able to overrule any executive’s moderation decisions.
