Facebook releases content moderation guidelines – rules long kept secret

A year after the Guardian revealed Facebook's secret rules for censorship decisions, the company has released a public version

A year after the Guardian revealed Facebook's secret rules for content moderation, the company has released a public version of its guidelines for what is and is not allowed on the site, and for the first time created a process for individuals to appeal censorship decisions.

The disclosure comes amid a publicity blitz by the company to regain users' trust following the Observer's revelation in March that the personal Facebook data of tens of millions of users was improperly obtained by a political consultancy.
