Hours after CEO Mark Zuckerberg spurred history by defending the rights of Holocaust deniers to post on Facebook, the company said it had begun removing misinformation that contributes to violence. “There are certain forms of misinformation that have contributed to physical harm, and we are making a policy change which will enable us to take that type of content down,” the company said in a statement. “We will be begin implementing the policy during the coming months.”

Under the new policy, Facebook will begin reviewing posts that are inaccurate or misleading, and are created or shared with the intent of causing violence or physical harm. The posts will be reviewed in partnership with local organizations including threat intelligence agencies, which Facebook says are in the best position to evaluate threats. Posts covered by the policy include manipulated imagery as well as text.
