I probably didn't make it clear enough (damn my brain), but I have absolutely no issue with it as a kink. I didn't read yours because it's just not my thing, but when it's the point of the story it doesn't bother me at all. It's when it's a throw-away line and treated as a joke that it gets to me and triggers flailing rants like this one.

Invasion of privacy as a kink = fine
Invasion of privacy as a joke = THINK OF THE CHILDREN!
My head = fun place to be.
