Prior restraint

Prior restraint is a constitutional-law term for state action that prevents speech from being published in the first place — as opposed to punishing speech after publication. U.S. First Amendment doctrine (Near v. Minnesota, 1931; Pentagon Papers, 1971) treats prior restraint as presumptively unconstitutional. Most other democratic systems are similarly skeptical, though the bar varies.

For offshore hosting, prior restraint is the worst-case scenario: a court orders a host to take down content before any adversarial proceeding has determined it's actually unlawful. Hosts in strong-First-Amendment jurisdictions (the U.S. for U.S. speech, Iceland and Switzerland for European speech) have the strongest legal posture against prior restraint. Hosts under more deferential regimes can be compelled to remove content under broader frameworks.
