While the largest tech companies will be at the table, some of those responsible for running anonymous internet forums known for extreme content - such as 8 Chan and 4 Chan - are not taking part in the summit. Anyone who commits one of several major infractions under Facebook rules-for example by linking to pro-terrorism propaganda-will now be banned from using Facebook Live for a period of time (such as 30 days) on the first offense. It is also broadening the range of offences that will qualify for one-strike suspensions.
The announcement comes as Jacinda Ardern co-chairs a meeting with French President Emmanuel Macron in Paris on Wednesday seeking to have world leaders and chiefs of tech companies sign the "Christchurch Call", a pledge to eliminate violent extremist content online.
It calls on "governments and private corporations to prevent the posting of terrorist content online, to remove it quickly when it does appear, and to prevent the use of live-streaming to broadcast violence", as the Irish Times reported.
Facebook, which dominates social media and has faced the harshest criticism for overlooking the misuse of consumer data and not blocking live broadcasts of violent actions, said it is toughening its livestreaming policies.

Facebook has come under intense criticism for its handling of the gunman's video on its platform. According to an account released by the Prime Minister's Office, he spoke about how governments could work with social media platforms to "stop the internet being used as a tool to organize and promote terrorism and violent extremism".
Additionally, Facebook also announced it would invest $7.5 million into new research partnerships with the University of Maryland, Cornell University, and the University of California, Berkeley, that are created to improve image and video analysis technology so it can also find videos that have been modified to avoid detection.
She said she herself inadvertently saw the Christchurch attacker's video when it played automatically in her Facebook feed.
The Christchurch, New Zealand, shooting, which was shown on Facebook Live, emphasized growing concern about online radicalization.
"There's no word on what the rules are, so that makes it very hard to determine whether or not posts and video content are in breach of the rules".
