Facebook Inc says it is tightening rules around its livestreaming feature ahead of a meeting of world leaders aimed at curbing online violence in the aftermath of a massacre in New Zealand.

A lone gunman killed 51 people at two mosques in the city of Christchurch on March 15 while livestreaming the attacks on Facebook.

It was New Zealand’s worst peacetime shooting and spurred calls for tech companies to do more to combat extremism on their services.

Facebook said in a statement it was introducing a “one-strike” policy for use of Facebook Live, temporarily restricting access for people who have faced disciplinary action for breaking the company’s most serious rules anywhere on its site.

First-time offenders will be suspended from using Live for set periods of time, the company said. It is also broadening the range of offences that will qualify for one-strike suspensions.

New Zealand Prime Minister Jacinda Ardern said the change addressed a key component of an initiative, known as the “Christchurch Call”, she is spearheading to halt the spread of violence online.

“Facebook’s decision to put limits on livestreaming is a good first step to restrict the application being used as a tool for terrorists, and shows the Christchurch Call is being acted on,” she said in an email from her spokesman. (NAN)
