"Facebook announced today that it’s updating its group privacy settings and working to better moderate bad content breaking the platform’s rules. The platform is renaming its confusing public, closed, and secret group settings to the slightly more straightforward public and private settings, with the option to make private groups visible or hidden to non-members. The new settings will also provide more control for admins and members, giving admins more moderation tools and members the option to see the group’s history and preview its content before accepting or declining an invitation.Facebook is simplifying group privacy settings and adding admin tools for safety | The Verge
The new group settings are also part of the Safe Communities Initiative that the company started two years ago, in an effort to monitor and detect bad content in Facebook groups. The announcement comes in the wake of recent findings that secret Facebook groups have been acting as gathering places for racist, offensive activity — one example coming from earlier last month, when ProPublica found a group of Border Patrol agents joking about migrant deaths."
