Some will know of "super-injunctions" being used here in GB by the well-known to protect their privacy and identity in some situations.
Been a lot of controversy about these being issued by the Courts, with the GB press banned from not only revealing the identities and actions of those concerned but also being denied the right to publish news that these injunctions even exist.
Much to my surprise, have just seen on Twitter that the Man Utd footballer Ryan Giggs is claimed by posters there to be the identity of the party known as CTB, in whose favour the GB High Court issued one of these super injunctions, and also read that the Twitter posts go on to claim was involved in an extra-marital affair.
Twitter is based in the USA by the way, and like CF, has its servers there, and Americans take their First Amendment Rights (freedom of speech, free press etc) very seriously.
