Facebook is known for how it deals with pornographic content and its stringent policy about pictures and shared content. One of the key factors to sustain the growth of the service is to ensure that the system is free from unpopular content. To that end, they have hired individuals to screen through all the flagged content and delete what they deem as inappropriate according to Facebook’s own rules and standards. That sometimes include people.
People that are considered to be a nuisance to the service or breach any of Facebook’s policies are immediately deleted and the reason for that is scandalized to the entire Facebook community. This is all done to ensure that the service doesn’t suffer the same fate as MySpace and its other predecessors which got swarmed with porn thus driving away professionals from their networks. Earlier, to a certain extent, the porn cops’ activities and judgments were based on actions and information that occurred within the Facebook platform and not on what happens to people’s real lives outside of Facebook but that seems to have changed recently.
