Facebook, with 2.2 billion users, disallows such things as nudity, the selling of guns, credible threats of violence, and direct attacks on people because of their race, sex or sexual orientation.

Hours after the Facebook founder's comments about Holocaust deniers aired on Wednesday, the company announced it will also start removing misinformation that could lead to bloodshed. The policy will begin in Sri Lanka and expand to Myanmar, where Facebook users have been accused of inciting anti-Muslim violence.
