In many places in the western world, facebook users are some 90 percent of everybody in a certain age group. So if it says anything about Facebook users, it says something about everybody. Facebook is approaching 2B users. Let's say that every 1/1,000 users per day posts something that somebody else flags or which the system flags because of the words used. Then it's some 2M posts or comments that are flagged. Facebook currently has 4,500 in the community operations departments ("moderators"). Each moderator then has to screen around 450 posts, which is difficult in an 8 hour shift. So obviously, that's not the way it works. They surely have algorithms that sort flagged posts with higher priority; more people flagging means it's more urgent, certain profiles are more urgent, for example people who have used violent language before, users with certain friends are more urgent, users at a certain age are more urgent, certain hours of the day are more urgent, post with certain words associated with violence or suicide are more urgent than posts with racist or sexist slurs or nude material etc. But even if they correctly identify a threatening suicide or hate crime, how do they prevent it? Shutting down a live video is one way, but contacting authorities would probably also be necessary. How do you do that when your users are spread over 100,000 different jurisdictions? It's a big task.
