I would shed no tears if FB profits went down, but...I think you're underestimating how big they are. Two BILLION users, in ~100 countries (each with its own standards on what is acceptable, legal, repulsive, etc.). If you had one moderator per 100 users, that would 20 million moderators. I don't think they could hire 20 million high quality moderators (there's only one dang, and we're not giving him up), and certainly not with 18.5 billion.
