My friend had a gf with 60k followers who got reached out by management. The management company basically sends a PPT showing how many users they would be able to convert and the earnings based on that and earnings after OF and Management cut.
They also tell all the creator has to do is send the pics they are comfortable with, and the management will arrange, post and add captions to maximize sales.
She probably got the same thing, saying to monetize her following and to send whatever she feels comfortable with. I also know some creators get guaranteed income so the management company keeps recycling content to sell more and more and sometimes makes it cheaper, so more people buy to hit those targets.
I hope someone sues the locked messages concept, especially the fact that if you unlock, the platform OF/Fansly/Fanfix just raise their hands saying we are not responsible. Like bro it's your platform, you release the funds to the creator, you are responsible.
