She was an anitwitter personality from a few years back, where there was a completely different "audience" for those kind of antics compared to the vtuber audience. You could say or do the most absurd shit and because of the comically-exaggerated nihilistic culture even the people who were in a position where they should be bothered would just meme about it; which is the complete inverse of /vt/ where everything is blown out of proportion and made personal, no matter how insignificant. This is a new, different kind of backlash that she probably just wasn't mentally prepared for.
I didn't mention this before because she hasn't done this in years, and doesn't seem interested in going back to it since she's in what seems like a normal relationship, but she used to be very... egirl-ish. I distinctly remember her posting lewd photos on at least one of her old, now-banned accounts. I realise this is a "source: I said so" thing, so here's her joking about it on her Hexa account with her long-time friend Syd
who I've also seen naked.
(If someone could archive that I'd appreciate it, neither of the usual sites are working for me right now)
EDIT:

I bring this up because in that community actual female women who posted their body in that community were treated as goddesses because 99% of their followers were horny single men - obviously that's also true with vtubers, but the "hot girl" buff isn't as strong when
everyone has a hot girl avatar. I think she's always been menhera, but this is the first time she's been exposed to the kind of things that push the specific buttons to cause a meltdown.
