Leaked documents on how Facebook deals with violent, explicit and harassing content, as published in the Guardian, further exposes the challenges the social network faces in policing the posts of its nearly 2 billion users. It also shows that its censorship problem may not be solvable any time soon. The Guardian’s report illustrated how stressful and fast-paced the environment is for Facebook’s content moderators. They often only have 10 seconds to review something, and the guidelines that govern what is acceptable on the site are not always consistent.
