Facebook has pretty much created a monster that’s impossible to tame:

How to successfully moderate user-generated content is one of the most labor-intensive and mind-bogglingly complex logistical problems Facebook has ever tried to solve. Its two billion users make billions of posts per day in more than a hundred languages, and Facebook’s human content moderators are asked to review more than 10 million potentially rule-breaking posts per week. Facebook aims to do this with an error rate of less than one percent, and seeks to review all user-reported content within 24 hours.
