Nearly 200 Facebook employees have signed a letter urging the company’s executives to address concerns that pro-Palestine voices on the social media site are being suppressed by content moderation systems. The letter, first reported by the Financial Times, urges the company’s leadership to introduce new measures that ensure pro-Palestinian content is not taken down, as critics claim happened during last month’s conflict in Gaza. They also want Facebook executives to set up an internal task force to “investigate and address potential biases” in both its human and automated content moderation systems.
