"In the UK, if someone publishes another's name and address on the web (without that person's permission), s/he is in breach of the Data Protection Act, and the law will descend on them like a ton of bricks. Don't you have a law like that in the US?"

Quick answer: I don't know. Does anyone know if there's a law against publishing someone's name and address on the web on the US?

Btw Rachel, are you sure that's covered under the Data Protection Act in the UK? My instinct is that unless the information was taken from the publisher's own database this is not covered under the act. I could be wrong, and am open to correction. But I don't think, if it is illegal to publish someone's N+A on the web in the UK, that it is the DPA that makes it so.
