Thanks for this unique insight; we have never heard this before.
But no. Why do people think this? Just because she is a fat, filthy glutton?
Hasn't she shown us time and again that she will wear ill-fitting clothes, lounge around half-naked, and look like a slob without any prompting whatsoever? Do you really think it takes one of these shadowy, mythological "feeders" about whom everybody seems to be an expert to order her to dress like that? Come on, that's how she always dresses. In five years of viewing her, I have yet to see any evidence of this network of feeders on her channel. She certainly has never directly acknowledged any secret feeder community, which is odd considering she is pathologically incapable of keeping her mouth shut. In her audience, I see a bunch of lumpen, fat, mentally-deficient middle aged women, who would prefer she not dress like that. But Chantal is incapable of doing what anyone wants, whether it is VIBs, feeders, or her family. She wouldn't take orders from a feeder, and she doesn't need to. She thinks up this stuff on her own, and it fits with her character perfectly. If it grosses people out, she likes it. Or, if it plays into her delusion that she is a skinny sex kitten, she likes it.
I am one who isn't an expert on feeders, but what I do know is that they do not seem to be attracted to her in the least. Feeders want compliant women they can force feed. They do not want defiant women who give them sass. They also do not seem particularly interested in shitting, farting, and burping; that is another fetish entirely.
Let's stop blaming her behavior on these phantom feeders, and put it squarely back on her shoulders, where it belongs.
