What's wrong with an OnlyFans contributor? It's a self-employed job that services a demand within the economy and pays taxes. It's pretty close to the ideal job an immigrant can have since the product is already globalized but the revenue is not - i.e. an OnlyFans influencer with an American audience who moves to America is now bringing that income back into the economy via taxes and spending, or if they have an international audience they are attracting foreign dollars into your economy and strengthening your currency position.

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.

Sex work (OF or otherwise) is unsavory, that's what. You can't stop it but there's zero reason we should be going out of our way to grant visas to sex workers.
