This is a serious concern of mine. If I lived alone I probably wouldn't care quite as much, but I have a family and I don't want anything to happen to them.
Calling him and telling him to take it back is something I'm strongly considering. BUT... That makes me feel like crap. So many people just let things go, don't want to get involved... and then nothing stops pricks like this from collecting this garbage. And what if he's doing more than just this?
Moral dilemma, for sure.
