Facebook has issued a “one strike” policy for users breaking its rules using the livestream feature, following the mosque terror attack in New Zealand.
The social network is toughening its stance on live broadcasts, with any accounts who violate Facebook's rules set to be punished from their first offence.
Users will be blocked immediately from using the platform's Live feature if they break the rules, for example by sharing a statement from a terrorist group with no context.
The decision arose after numerous videos of the attack in Christchurch, which killed 51 Muslims and injured 50 during Friday prayers on March 17, were removed from Facebook.
Guy Rosen, Facebook's vice-president of integrity, said: “We recognise the tension between people who would prefer unfettered access to our services and the restrictions needed to keep people safe on Facebook.
“Our goal is to minimise risk of abuse on Live while enabling people to use Live in a positive way every day.
Facebook has also pledged £35.8 million towards research to improve its ability to automatically detect offending content as well as ways to distinguish between people who share manipulated content and those who create them.
Mr Rosen added: "This work will be critical for our broader efforts against manipulated media.
"We hope it will also help us to more effectively fight organised bad actors who try to outwit our systems as we saw happen after the Christchurch attack."
Google, Facebook, Microsoft and Twitter are taking part in a summit in Paris next week to address terrorist and violent content online.
