The thing is I think too many people have no common sense (my favorite teacher used to say common sense is not that common). You do't publish naked pictures. I do not need a law for that, come on.
If people or objects are not allowed to be photography why are they in the public domain.
People with a photographic memory should all be sued and thrown in prison, those thieves.
Finding old photos and showing them to the world brighten up our lives. They can be shown, and who knows maybe the grandchildren find some old photos of their long lost grand parents.
