A federal court has blocked Utah's law requiring adult websites to block VPN users or identify their physical location, ruling that the law likely violates the US Constitution. The law was deemed to be a technical impossibility, as it would require websites to know every visiting user's physical location and block those in Utah. The Electronic Frontier Foundation (EFF) had submitted comments to the Utah Department of Commerce, detailing how the law would undermine user privacy and security worldwide. The court's decision sets an important precedent for state lawmakers not to weaponize age verification to force dragnet tracking or undermine essential security tools.
