Online strip clubs which sells emotionally stunted young men and underage boys the delusion that the stripper is actually interested in them.

The fantasy that, if only they visit every day and keep tipping her, she'll eventually notice them, and fall in love with them, and then he will be able to rescue her away from this sordid lifestyle, and she can turn over a new leaf in a romantic fairy tale perfect traditional marriage, and they'll have two kids, a dog, and a house in the suburbs, with a white picket fence.

And if that wasn't bad enough, not only do these men never actually get to see her physically, in person, many of them are slowly acclimatised into degenerate fetishes such as:

"Financial domination", where they shower women with financially irresponsible sums of money in exchange for the benefit of her sexually demeaning and degrading them,

Good ol' fashioned cuckoldry, where they pay strangers on the internet to have sex with the one women they want to have sex with, but who would literally rather have sex with anyone else except them.

Before OnlyFans was a thing, I didn't care what adult men and women did in their own bedrooms (or studios) as long as it was all consenting.

But witnessing the birth of this industry changed my mind. It is designed to optimise the exploitation of young men who are so desperate for a relationship, but have such a compelte absence of contact with females in their lives, that they have to resort to actresses fleecing money from them as the closest substitute, despite how it is literally nothing at all like the real thing.

These men grow up through school being rejected by girls, by the time they hit tertiary education they end up as loners who can't even hold a conversation with one. They've never been on a date to a coffee store or a movie. They've never walked through a park and held hands with a girl. Their forays into online dating would have been more successful if they were literally invisible. The few hobbies they do have, are completely devoid of women. The only women they come into contact is the lady at the checkout till at the convenience store.

tl;dr: There are men who are so emotionally and socially stunted, that the only way they can get women to glance at them is to pay them money. This is apparently an incredibly lucrative business.

You pay a subscription and you get to see them, but also talk to them.

It's as I said, a way to monetize the dehumanization campaign they've been running for decades.
