Distinguishing Fair Housing Council of San Fernando Valley v. Roomates.com, LLC (9th Cir. 2008) 521 F.3d 1157, this decision holds that section 230 of the Communications Decency Act (47 U.S.C. § 230) immunizes internet service providers whose only content-enhancing action is to apply a neutral algorithm to refer users to third-party content that appears related to items they have recently viewed or are currently searching for.  However, claims that Google funneled a portion of its advertising revenue to ISIS-related content used to recruit new ISIS volunteers was not immunized by section 230.
