Well, thanks to Facebooks "View As" functionality, I recently discovered that their privacy setting "Only Me" does not work for only me, if another person is tagged in the picture. Meaning that if I have a picture with my ex somewhere in profile, set to "Only Me", it actually means "Only me... and her".
