I think the people willing to pay $30 for a video and $150 are largely the same people. With those numbers, even if half her customers drop off, she's still making more money. plus she now has the option to do flash sales at $30-$50, and if she wants, she can just make less content for periods of time and coast of her simps.
It's so wild, she does hardcore videos and then stop completely and post barely lewd pictures and then comes back with a price-tag like that...
