We don't really know if he is paying her to not do Onlyfans. When some of the court documents leaked it did say she had threatened him in the past that she would make an Onlyfans if he didn't pay her. So there is some precedent.
It would explain why she hasn't made one despite her streaming career pretty much being over and no real other way for her to make money outside of escorting. Despite the fact she has openly talked about making an Onlyfans/Fansly and very much enjoys showing her tits off.
This chick has had the entire internet call her fat, ugly, and a whale. Of course she is going to want to change that and now have guys drooling over her and being called hot cause her tits are out and she is using 1,000 filters. Especially a lot of his fans. She wants this. That is why people feel the second he might stop paying her, she is going to go all in showing her tits, body, etc, and begging for money.
