The following is tin foil, but what if Yaba simply pushed YouTube on the wrong day?
Several years ago (2019-2020?), there was a change to YouTube's bullying/targeted harassment policy, and we saw reactors scrambling to "diversify" their content (I don't cover just one fat chick -- I cover three!) Yaba even announced she was going to do a weight loss journey, and she briefly switched to reactions without using Chantal's footage (obviously, neither worked out for her). When it was clear that YouTube wouldn't enforce the policy (evenly, anyway), reactors went back to business as usual (and no, I don't think the occasional video about camper living or some woman with 12 kids counts, ha ha).
Then there was Chantal's drug phase, and Yaba et al. briefly claimed the high road, presumably bc the content might get demonetized. This might be the beginning of the cutesy euphemisms, which still get under my skin (meth=math, rape=grape, PDFiles, etc.) Once it was clear YouTube didn't care about it, they came back. There was also recent concern about this, because someone's reaction video got flagged for "disordered eating."
The past few months, Yaba's streams have gotten increasingly grotesque. She obsesses in graphic detail over Chantal's bowel movements, her genitals, her sexual habits, etc. She's even said, "Oh, this one's getting demonetized." Yaba's talking extensively about drugs, drug addiction.
Which is not to say someone didn't "pull the trigger." I do, however, believe certain reactors have been rolling the dice with YouTube, either hoping they don't get age-restricted or assuming they won't. Still, YouTube's wiped out entire communities over the years -- true crime, "queer youth education" (think Riley J. Dennis, Lindsay Amer), etc. I'm not saying YouTube is coming for Gorl World per se, but I wouldn't think any of them would want YouTube scrutinizing them.

@StrawberryDouche,
@Twinkie, you know, there's nothing worse than a beautiful, crackpot theory destroyed by simple reality (I say simple, but this one involves international assassins), ha ha.
