The "Facebook Files" - a selection of more than 100 internal training manuals, spreadsheets, and flowcharts - provide a rare insight into how Facebook's moderation team work and what they look out for.
Read the full Guardian report here. YouTube took the video down nearly immediately, but it took administrators two weeks to remove it from Facebook, where it received thousands of shares and comments.
Facebook Live, which allows people to livestream video of whatever they wish, has seen several high-profile acts of violence since it was released. In one of the slides, Facebook said that users livestreaming or posting videos of self-harm are "crying out" for help online, and therefore shouldn't be censored.
Monika Bickert, Facebook's head of global policy management, told The Guardian that Facebook was "a new kind of company". This requires a lot of thought into detailed and often hard questions and getting it right is something we take very seriously. The social media company reviews more than 6.5 million reports of potentially fake accounts a week, the newspaper added. The guideline also says that "experts have told us what's best for these people's safety is to let them live-stream as long as they are engaging with viewers".
Part of the rules revealed say phrases like "Someone should kill Trump" should be taken down because it references a Head of State. Facebook has brought to the public's attention various cases of police brutality, and while such videos are disturbing, they may be helpful in exposing social problems. When it comes to child abuse, some pictures of bullying and non-sexual physical abuse of children do not have to be deleted or "actioned", unless it has a celebratory or sadistic element.
Facebook has said in the past that it is in a unique position to do more about the suicide epidemic. Other disturbing and violent comments, however, such as "fuck off and die" and - brace yourself for this next one - "to snap a bitch's neck, make sure to apply all your pressure to the middle of her throat" are accepted on the platform.
"Generic" or "not credible" threats - and it was not clear how Facebook arrived at a definition of "not credible" - included "I hope someone kills you".
Videos of abortions are allowed, as long as there is no nudity.
The company recently shifted the secret policy to allow livestreams of self-harming, but to remove the footage if the person was deemed to be beyond "help" - unless, of course, the incident was "newsworthy".
In a similar stance, videos uploaded or recorded live showing violent deaths will likely remain in place, as Facebook believes it will help raise awareness of people with mental illness.
"Handmade" art showing nudity and sexual activity is allowed, the documents show.
The revelations of how the website moderates content that can be considered abusive, violent or sexualised - including pornography and self-harm - appear inconsistent and confusing.
