An interesting case highlighted by Eugene Volokh at the Volokh Conspiracy: a court bans a father from making any comments about his ex-wife in a public forum.
If the father says anything about the mother in public, he could be sent to jail for contempt of court. The order isn’t limited to banning libelous statements (though I think even such a much narrower ban would itself pose constitutional problems, especially under Pennsylvania law), nor is it even limited to statements about minor children (though even that sort of order strikes me as constitutionally impermissible). Rather, the court order categorically orders the removal of a Web site, and prohibits all public statements — factually accurate or not — by one person about another person.
I guess in Pennsylvania the First Amendment doesn’t count for much anymore.
