Section 230 of the Communications Decency Act barred plaintiff’s unjust enrichment, negligence, and UCL claims that Facebook for allowing third parties to post fraudulent ads on Facebook.  Those claims sought to impose liability on Facebook as a publisher or speaker of the false ads.  However, plaintiff’s breach of contract and breach of implied covenant claims based on Facebook’s alleged promises to filer ads were unrelated to Facebook’s status as a publisher or speaker and so escaped section 230 immunity.
