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, letting the law remain enforceable while litigation continued. 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. Status update: after the district court granted NetChoice a renewed preliminary injunction in June 2025, Mississippi again appealed, and a three-judge Fifth Circuit panel heard oral arguments for the second time on Feb. 3, 2026, with no ruling issued as of this update.
