The original article mentioned "softcore" porn, like old school cinemax movies where it's porn, but thinly veiled into an actual movie.

Not like hardcore 10 minute porn movies, just semi-skeevy smut that you'd rather not have other people know you're watching. (50 shades?)

It doesn't seem like a huge stretch. If somebody had a stored collection, and didn't share the server with anybody, why not point Plex at that folder? There's even an *arr for it, so it fits right into the usual stack.

People who haven't yet discovered StashBox.

Thank you! This is what I was wondering too!
