An initiative called the Christchurch Call, led by the governments of New Zealand and France, calls on other world leaders and tech giants to be more vigilant in policing live streams on social media platforms. While the United States government has refused to endorse the effort, Facebook has agreed to make some minor changes to the way it polices its platform.

Two months after the horrific mass shootings at two Christchurch mosques that left 50 people dead, Facebook has imposed what it calls a “one strike policy” that will determine who can use its live-streaming service.
