Facebook has announced a new policy that allows it to take out networks of accounts engaging in "coordinated social harm".  

The company said the change could help the platform fight harmful behaviour it wouldn't otherwise be able to fully address under its existing rules, reports Engadget. 

Unlike "coordinated inauthentic behaviour", which is Facebook's policy for dealing with harm that comes from networks of fake accounts, coordinated social harm gives the company a framework to address harmful actions from legitimate accounts, the report said.
