From the descriptions of the work in this article it sounds like Facebook is actively choosing to have the same moderator re-moderate the same content over and over. At that point it almost seems like intentional malice from Facebook rather than a "developer oversight". Surely the first time a video has been flagged it should be trivial to identify further uploads of that video? The only reasonable explanation I can imagine is that Facebook is doing everything they can to avoid having to implement a "Content ID" system like YouTube. Now why exactly they don't want to do that can only be speculated.
