Meh, it's pretty much the flip side of "young woman likes to keep old guy company", it's just that people are more exhibitionist since the advent of the internet. A few decades ago, they might have been more discreet about it, and people might have chosen to politely ignore things, and pretend he's just her caretaker.

I remember that case with a young woman and older man some years ago that almost exactly echoed a storyline from WKRP in Cincinnati re: Jennifer and her friend.
