In the swirl of scrutiny surrounding the big Silicon Valley tech companies and with some in Congress declaiming that Section 230 of the Communications Decency Act (CDA) should be curtailed, 2019 has quietly been an important year for CDA jurisprudence with a number of opinions enunciating robust immunity under CDA Section 230. In particular, there has been a trio of noteworthy circuit court-level opinions rejecting plaintiffs’ attempt to make an “end run” around the CDA based on the assertion that online service providers lose immunity if they algorithmically recommend or recast content in another form to other users of the site.

This week, in a case with an unsettling fact pattern, the Ninth Circuit made it a quartet – ruling that a now-shuttered social networking site was immune from liability under the CDA for connecting a user with a dealer who sold him narcotics that culminated in an overdose. The court found such immunity because the site’s functions, which included content recommendations and notifications to members of discussion groups, were “content-neutral tools” used to facilitate communications.
