"Anti Muslim hate speech is absolutely relentless on social media even as platforms crack down on other extremist groups," 18 March 2019

Facebook, YouTube, and Amazon moved to remove or reduce the spread of anti-vaccination content... [and] largely eradicated ISIS terrorists and made inroads to remove white supremacists from their services, and worked to keep them off. But through all this, anti-Muslim content has been allowed to fester across social media. For years, Muslims endured racial slurs, dehumanizing photos, threats of violence, and targeted harassment campaigns, which continue to spread and generate significant engagement on social media platforms even though it's prohibited by most terms of service... Researchers say Facebook is the primary mainstream platform where extremists organize and anti-Muslim content is deliberately spread... “Islamophobia happens to be something that made these companies lots and lots of money,” said Whitey Phillips, an assistant professor at Syracuse University... She said this type of content generates engagement, which in turn keeps people on the platform and available to see ads.

In an emailed statement, a Facebook spokesperson said the company has been taking down content specific to the attack [at two mosques in New Zealand] — it said it had removed 1.5 million videos of the attack in the first 24 hours — but addressed questions about anti-Muslim hate speech by linking to a blog post from 2017... Facebook has said it has been actively removing comments from the platform that "praise and support" the New Zealand attack, but the company said nothing of stepping up efforts to eradicate other anti-Muslim speech spread on its platform.
