In March 2019 , the perpetrator of the Christchurch mosque shootings in New Zealand used Facebook to stream live footage of the attack as it unfolded . Facebook took 29 minutes to detect the livestreamed video , which was eight minutes longer than it took police to arrest the gunman . About 1.3 m copies of the video were blocked from Facebook but 300,000 copies were published and shared . Facebook has promised changes to its platform ; spokesman Simon Dilner told Radio New Zealand that it could have done a better job . Several companies , including the ANZ and ASB banks , have stopped advertising on Facebook after the company was widely condemned by the public . Following the attack , Facebook began blocking white nationalist , white supremacist , and white separatist content , saying that they could not be meaningfully separated . Previously , Facebook had only blocked overtly supremacist content . The older policy had been condemned by civil rights groups , who described these movements as functionally indistinct . Further bans were made in mid-April 2019 , banning several British far-right organizations and associated individuals from Facebook , and also banning praise or support for them
