The secret of Onlyfans is not to get a lot of guys into you. It's to get ENOUGH guys into you. You want to get just enough guys that are into anything you do cause it's YOU, Then you can sell them anything. The trick with Onlyfans is to get some of your subs to develop a parasocial relationship with you. That requires a combo of the girl and the agency. The girl with her content whether that be YouTube, Instagram, TikTok, Twitch, etc. That is what draws guys in. The agency then selling you that you can continue that parasocial relationship with said girl by buying her Onlyfans content.
A guy who doesn't have a parasocial relationship with a girl will be much more critical of any content and will balk when it's clear her agency is now scamming. But a guy who has a parasocial relationship with a girl won't question anything and will pay. And those are the guys the agencies are trying to get.
