Extracting money from horny young men with an illusion of intimacy/friendship just doesn't seem ethical. Or good for society as a whole.
Especially when you've got streamers using sites like Twitch, aimed at younger gamers, promoting their OnlyFans porn.
The regular porn industry is bad enough (https://traffickinghub.com/), but at least the content is non-interactive, there's no pretence of friendship/connection.
Most users understand that there is no real friendship.
Just like people understand that the violence in movies is fake.
What makes an onlyfans contributor worse than an actor in a violent movie?
