Mississippi Walker Montgomery Protecting Children Online Act (House Bill 1126)

Mississippi's HB 1126 requires social media platforms to verify users' ages, obtain parental consent for minors and shield minors from 'harmful' material, backed by $10,000-per-violation penalties. NetChoice - whose members include Reddit - sued (NetChoice v. Fitch) and won a district-court injunction, but the Fifth Circuit stayed it and on Aug. 14, 2025 the U.S. Supreme Court declined to block enforcement. Justice Kavanaugh, writing separately, listed Reddit by name among the platforms the district court had found the law unconstitutional as applied to, while noting the law is 'likely unconstitutional' under current precedent.
