““Facebook puts users in a near-impossible position by telling them they can’t post about dangerous groups and individuals, but then refusing to publicly identify who it considers dangerous,” said Faiza Patel, co-director of the Brennan Center for Justice’s liberty and national security program, who reviewed the material. The list and associated rules appear to be a clear embodiment of American anxieties, political concerns, and foreign policy values since 9/11, experts said, even though the DIO policy is meant to protect all Facebook users and applies to those who reside outside of the United States (the vast majority).
