In a blog post, Facebook said that anyone who breaks its rules will be restricted from using its "Live" feature. Any activity on the social network that violates its policies, such as sharing a terrorist group's statement without providing context, will result in the user immediately being temporarily blocked.
Facebook will ban first-time offenders from using the feature for set periods of time; the list of offences that could entail such a punishment will also be broadened.
In response to the March 15 terror attack, Facebook has already banned white nationalist and white separatist content, and recently removed controversial figures for promoting violence or hate including Alex Jones, Milo Yiannopoulos and Laura Loomer. Facebook did not specify all the rules that it will use to enforce the new one-strike approach, but pointed to current community standards that prohibit spreading terrorist propaganda on the social network.
