I think whatever contract she signed with Fansly probably has some extra benefits it. Outside of the ratman jokes, probably some sort of equity in company, paid for appearances as a brand ambassador and so on.
I always find it funny when she says that it's so much better. If it's so much better then why aren't all her friends streaming on it full time or better yet more people are streaming on it? I'm sure for content purposes people like it. i hear they allow a lot more freedom then OF does.
