Can a state law prevent a social media site from publicly posting accurate age information about individuals in the entertainment industry—even if that information is posted by users? The California legislature and Governor believed it was permissible, and the legislation went onto effect on September 24, 2016 (Cal. AB 1687, adding Cal. Civ. § 1798.83.5).  Five months later, a federal judge temporarily enjoined the government from enforcing that law, in IMDb.com Inc. v. Becerra, No. 16-cv-06535-VC (N.D. Cal. Feb. 22, 2017).
