Actually, the 1992 Act IS limited to media publications, sorry:
"Anonymity of victims of certain offences.(1)Where an allegation has been made that an offence to which this Act applies has been committed against a person, neither the name nor address, and no still or moving picture, of that person shall during that person?s lifetime?
(a)be published in England and Wales in a written publication available to the public; or
(b)be included in a relevant programme for reception in England and Wales,
if it is likely to lead members of the public to identify that person as the person against whom the offence is alleged to have been committed."
However, any court orders made by a judge pre or during trial e.g. under the Contempt of Court Act 1981 cover everyone and all kinds of dissemination of the information. If victims have reason to fear that there will be a naming campaign (such as happened in that awful Chad Evans case) they can apply for appropriate court orders, though you'd hope prosecutors would do it for them.
