I really don't think anything is going behind the scenes. I started using her stream as background noise when I work cause I like her voice but seeing how much money she gets donated, I kinda got interested in the psychological aspect of why would someone drop so much money on a random girl that will never meet. So I did some research and became a bit more observant of her viewers.
I think her average donator isn't some rich guy who wants to see her naked. It's a young dude 20-35 years old, socially awkward who don't have much success with women, that developes a parasocial relationship with her. 90% of her donations would come from a rotation of 5-10 guys who stay for a few months and keep throwing money at her so that she keeps responding to their DM's and maybe send a selfie here and their and pretend she's interested in the problems they are confessing to her. She will basically pretend to be their online girlfriend. I doubt she's sending nudes or whatever cause at this point it would certianly leak and also she doesn't have to.
There was a moment a few weeks ago when one dude dropped a 1k donations just to apologize for something he said in the DM's with her and said that he was crying all day after making her upset.
Also some time back one dude would donate like 10k in a span of like a week. He had a pretty unique username so I googled him and turns out it's his real name and last name. Found his socials and it's just some normal 20-25 year old guy who looks like a bit socialy inept. He also said in the twitch chat that he has 2 jobs and that all the money from his second job get donated to her. He also keeps donating these weird text to speech donations of how they're basically married and how he pretends all the time that she's with him.
I think she's an absolute killer in extracting money from these dudes. Give them attention back when they donate, withdraw it or ignore them if they don't or purposely start conflicts with them so they apologize with donations. She treats twitch as a money making machine and will absolutely manipulate these guys that they donate to her. She's become really good at it.
Also considering she's got dudes absolutely obsessed with her, her infosec is really bad, one day someone will end up at her house looking for her.
