If those show up and they are flagged for review—a user flags them or they're spotted by our systems—we have a team of 10,000 who review videos that have been flagged to see if they violate our policies.
If the context is that something is obviously a clip from a movie or a piece of fiction, or it's a presentation of an issue in a particular way, we have to carefully weigh whether or not this will be recognized by our users as a reflection of cultural or news content, as opposed to something that's explicitly designed to promote and incite hatred.
