My wife bought it for me as a present once misunderstanding what it was. I looked at those subs once and then never again

I still appreciate the effort, but by far the most useless gift she's ever given

It's the only thing the people in that sub necessarily have in common, and is the theme of the sub. Very very pointless.

I think it's more likely that they paywall some of the NSFW subs than try to make more subs like r/lounge.
