Not a stupid question at all ... but I don't know the answer. Over here (England), it is not necessary for there to be a designated imprimatur (is that what you mean?) for published works. Instead, if you are offended by a publication, or it breaks the law, you go after the person with the deepest pockets, be that the author, the publisher, the editor, the broadcaster, the director/producer, or even the distributor or retailer.

All of the profits, however, go to the publisher.
