So if I write down my address in my pocket diary and I haven't asked your permission I'm in breach of the law? Or if some shady character doesn't want a journalist to have his name in his contact book, he can force him to remove it? I can see some difficulties making that stand up in court.

Still looks clear enough that, in this case, once Brendy has asked to be removed from a mailing list, however acerbically that demand may have been expressed, WYSIWYG has no legal option but to comply.

Always assuming that the law in the States is similar, which I imagine it would be.

Here is a link to lots of stuff about that Maybe someone who understands things like that might have a look through it and clarify the position.
