Safety is Facebook's top priority. They remove content and may escalate to law enforcement when they perceive a genuine risk of physical harm, or a direct threat to public safety. You may not credibly threaten others, or organize acts of real-world violence.

Organizations with a record of terrorist or violent criminal activity are not allowed to maintain a presence on Facebook. They also prohibit promoting, planning or celebrating any of your actions if they have, or could, result in financial harm to others, including theft and vandalism.
