I totally agree. If she was doing sex work of any kind, she'd be as insufferable and persistent with her virtue-signalling about it as she currently is with her claims to be anything but a straight woman. As a Narcissist, she hashtags the shit out of SocJus issues that either directly affect her (fat acceptance), or that she wants you to believe directly affect her (her current pretense at "queerness"), but ignores everything else.
Also, the images and captions on her Insta are all tailored to appeal to her female fanbase; if she was trying to attract feeder clients, at least some of them would take on a different tone. I don't see that she's trying to attract men at all right now; she's just trying to maintain her status as the ultimate Queen Bee fat girl living her best life, who all the other fat girls can only aspire to.
