Chantal is dumb, but she's also essentially a toddler (who weighs enough to be 20 toddlers). After cultivating her totalitarian hugbox on Youtube, she probably cannot imagine how many people are "haters", and whether for genuine fetish or hilarity, would happily request her to perform depraved humiliation for cash. She doesn't want that. She wants to be perceived as sexy, seductive, this manic pixie dream girl keeping it real, eating a party sized meal because she's cool like that.
She wants enablers that don't make her feel perceived and dissected as feeders do. A lot of people seek out sex workers for the so-called Girlfriend Experience, but strangely, Chantal is doing this for the Boyfriend Experience. She wants to lurch around in ill-fitting underwear, a sudden surge of glee and effort for a partner who truly loves her for her. She probably thought that people willing to pay would simulate the sort of kindness, bordering on worship that she wishes she'd get from a partner, and that she grudgingly barely receives at all through the lowest common denominator of Peetz' level of passive acceptance of her behaviours.
The kind of people who want what she's selling do not worship obese bodies, whatever they say. They love the illness, the fat rolls, the sick, the infirm, a human body reduced to slovenly sow.
