I do not use Facebook, or any other "voluntary data surrender services". I sent some personal photos (snail mail) to a family member with instructions not to copy them. My wife logged onto facebook and found that they had scanned them (poorly!) and uploaded the images to facebook. These are photos that I probably would not have let out of my darkroom if I knew that doing so would have their images lodged on some companies servers. The whole thing makes me wonder what happens now. I suppose that Facebook's TOS says what they can do with uploaded images, since the uploader is an account holder and bound by the TOS. But what if someone uploads images that they themselves are not allowed to be copying? Does that change anything?
