She knows that. Just like every other Twitch and OF creator. Each has their own limit of how much they are willing to show and/or willing to do and how much they are wanting to make and get simps to sub and donate to them.
She clearly knows her figure is why most people watch her. I'd bet she fluctuates all the time between enjoying the attention and not. She uploads a photo because it looks nice, but then feels like she doesn't want all the comments to be just about her body and deletes it. Or, she does it because she knows the simps are watching and will see it immediately, save it, and it'll feed their thirst, while regular people are none the wiser if they see her social media.
Whatever she makes now from streaming is probably what she's comfortable with (averaging out to about 30-40k viewers per video means pretty high ad revenue, and then add subs + donations + sponsors - if some of the numbers online about twitch streamers are to be believed, she is making
at least $20k/month), especially as generally her content is pretty low effort (she barely games, answers chat, watches shows), so maintaining the thirst from simps by teasing and feeding every now and then is all she really needs to do.
She's not dumb - she
knows she can make bank if she started an OF, but that's not what she wants. Sincerely doubt she'll ever go that route.
