Numerous complains has peppered the press lately about Facebook’s moderating policies, after some disturbing videos and photos were shown online.

Now, the Guardian has shed some light to what exactly happens behind the scenes and what are the policies behind moderating content containing hate speech, terrorism, pornography and self-harm on its platform.

As Facebook grew in size, so does the challenges. In fact the UK based newspaper reported that Facebook’s moderators often have just ten seconds to make a decision. The social media company reviews more than 6.5 million reports of potentially fake accounts a week, the newspaper added.

New challenges such as “revenge porn” have overwhelmed Facebook’s moderators. “Facebook cannot keep control of its content,” a source told the Guardian. “It has grown too big, too quickly.”

Many of the company’s content moderators have concerns about the inconsistency and peculiar nature of some of the policies. Those on sexual content, for example, are said to be the most complex and confusing. Facebook had no specific comment on the report but said safety was its overriding concern.

“Keeping people on Facebook safe is the most important thing we do. We work hard to make Facebook as safe as possible while enabling free speech. This requires a lot of thought into detailed and often difficult questions, and getting it right is something we take very seriously”, Facebook’s Head of Global Policy Management Monica Bickert said in a statement.

Facebook confirmed that it was using software to intercept graphic content before it went on the website, but it was still in its early stages.

The leaked documents included internal training manuals, spreadsheets and flowcharts, according to information seen by the Guardian. Apparently, self harm was acceptable for live streaming, because it “doesn’t want to censor or punish people in distress.”

Facebook moderators were recently told to “escalate” to senior managers any content related to “13 Reasons Why,” the Netflix original drama series based on the suicide of a high school student, because it feared inspiration of copycat behaviour.
