Leaks expose Facebook moderation policy

How Facebook censors what its users see has been revealed by internal documents, BBC News reports, citing the Guardian.

It said the manuals revealed the criteria used to judge if posts were too violent, sexual, racist, hateful or supported terrorism.

The Guardian said Facebook's moderators were "overwhelmed" and had only seconds to decide if posts should stay.

The leak comes soon after MPs said social media giants were "failing" to tackle toxic content.

The newspaper said it had managed to get hold of more than 100 manuals used internally at Facebook to educate moderators about what could, and could not, be posted on the site.

Facebook has not commented on the authenticity of the documents seen by the newspaper.
