"In October 2018, Cloudflare stood out by continuing to support the chat platform Gab–infamous for racist chatter, including a post by Robert Bowers, who was charged with murdering 11 people in a Pittsburgh synagogue on October 27. Infrastructure companies like hosting provider Joyent and domain-name registrar GoDaddy dropped the site. But Cloudflare held on and continues to support Gab. In December, a Huffington Post article reported that the company serves at least seven groups on the U.S. State Department’s list of foreign terrorist organizations, including al-Shabab, the Popular Front for the Liberation of Palestine (PFLP), al-Quds Brigades, the Kurdistan Workers’ Party, al-Aqsa Martyrs Brigade, and Hamas. 'I know that frequently when we’re talking about content issues, this can become muddled in terms of: Well, what is offensive content?' says Joshua Fisher-Birch, a content review specialist with the nonprofit, nonpartisan Counter Extremism Project (CEP). 'We’re focusing on the worst-of-the-worst content here, which is specifically terrorist organizations, which is specifically extremist organizations that explicitly want to cause violence.' CEP has sent letters to Cloudflare since February 13, 2017, warning about clients on the service, including Hamas, the Taliban, the PFLP, and the Nordic Resistance Movement. The latest letter, from February 15, 2019, warns of what CEP identified as three pro-ISIS propaganda websites."
