Perhaps more relevant to the data retention laws, would be a site sharing passport numbers, names and addresses of EU citizens, perhaps collected at stays at motels/hotels across the US? The site might host them for free - but keeping/sharing that data without consent wouldn't be allowed under EU law. The particular example would probably also be illegal according one or more US laws (state or federal) -- but I think it is still more interesting than the rather silly things people get hung up on?
