they don't need to, that's the thing
Velvet would have made a fortune if she'd just done a sextape a few years ago, she would certainly have made millions if she had gone to OnlyFans during 2020/2021 when it peaked
but she also didn't make anywhere near as much money as the likes of Mandy/Macey during her career, so she's doing something now that works for her financially, whilst knowing she's not going to be back on TV screens any time soon. but Macey is playing it safe, she's clearly hopeful of further TV work down the line, and doing full-blown hardcore content is going to backfire for her TV hopes, so she just won't do it, even behind a paywall
but she also knows that she just needs to make it sound like it's hardcore and people will pay. and that's just misleading people in my opinion
