Facebook will begin removing from its platform false information that is intended to incite violence and other physical harm.

“Reducing the distribution of misinformation—rather than removing it outright—strikes the right balance between free expression and a safe and authentic community," a Facebook spokesperson said in a statement to CNBC. "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. We will be begin implementing the policy during the coming months.”
