The alt-right is having a bad week. Apple, Facebook, Spotify, and YouTube all removed Alex Jones’ Infowars podcasts and pages from their various platforms. Now, Microsoft has put Gab.ai—a Twitter alternative popular with America’s political fringe—on notice.

Microsoft told the service—which is largely an alt-right cesspool of people who have already been banned from Twitter—that it must remove hate speech that incites violence or lose access to Microsoft’s Azure cloud computing service, which hosts the platform.

Microsoft pointed to two posts from Gab user Patrick Little, one that calls for the “complete eradication of all Jews” and the other which calls for their death by torture: “After an initial review, we have concluded that this content incites violence, is not protected by the First Amendment, and violates Microsoft Azure’s acceptable use policy,” a Microsoft spokesperson told Motherboard. “Microsoft notified Gab.ai of this substantial concern and advised that it remove this content or respond to Microsoft within 48 hours, or potentially risk suspension of its service on Azure.”

Gab founder Andrew Torba posted a screenshot of a notice he got from Microsoft that says "continued violation of the Microsoft Azure Acceptable Use Policy may result in the suspension of your deployments." Torba posted a message on Gab asking Little if he would voluntarily delete the posts, but has not taken any action against him or his posts yet; Gab paints itself as a "free speech" alternative to Twitter. Torba said he would not be giving interviews on the subject.
