Beginning in August 2017, the Myanmar security forces undertook a brutal campaign of ethnic cleansing against Rohingya Muslims. This report is based on an in-depth investigation into Meta (formerly Facebook)’s role in the serious human rights violations perpetrated against the Rohingya. Meta’s algorithms proactively amplified and promoted content which incited violence, hatred, and discrimination against the Rohingya – pouring fuel on the fire of long-standing discrimination and substantially increasing the risk of an outbreak of mass violence. The report concludes that Meta substantially contributed to adverse human rights impacts suffered by the Rohingya and has a responsibility to provide survivors with an effective remedy.
