Reuters found more than 1,000 examples of posts, comments and pornographic images attacking the Rohingya and other Muslims on Facebook. A secretive operation set up by the social media giant to combat the hate speech is failing to end the problem, writes Steve Stecklow. In a recent report on the Rohingya crisis, Marzuki Darusman, head of the United Nations Fact-Finding Mission on Myanmar, said Facebook “substantively contributed to the level of acrimony and dissension and conflict” in Myanmar. In an interview with Vox’s Ezra Klein, Facebook CEO Mark Zuckerberg said his company was taking the issue “really seriously”. In April, activists representing six civil society organizations, criticized Zuckerberg in an open letter, saying he had mischaracterized Facebook’s response to violence-inciting messages in Myanmar and had not devoted sufficient resources to enforcing its hate speech rules in the violence-stricken country.
