This report details Facebook’s damaging impact on Muslim communities in nine countries and demonstrates how Facebook has willfully ignored the dangers posed by anti-Muslim content to the welfare of Muslims across the globe. Facebook’s own civil rights audit, completed in 2020 after a nearly two-year process that came only after sustained pressure from human rights groups, singled out anti-Muslim hate on the platform as a longstanding problem. The auditors wrote, “the organization of events designed to intimidate members of the Muslim community at gathering places, to the prevalence of content demonizing Islam and Muslims, and the use of Facebook Live during the Christchurch massacre,” created an atmosphere where “Muslims feel under siege on Facebook.”
