Is it considered really bad Facebook etiquette to share strangers' family pics on your page?

I have this one Facebook friend who's a woman in her 50's who does this all the time for some reason. She actually goes on the pages of people who aren't even friends with her and shares photos of their family (usually their kids), houses, pets, cars, etc for no apparent reason. Just the other day she shared a photo of a little girl on her page from a stranger's profile, and she's started doing it to my friends, which kind of pisses my off. Is this bad FB etiquette, and can people be removed from FB for doing this?

once you put anything on the internet, its fair game for who ever wants to use it
