It's easier to appeal as a cartoon character than an IRL woman, especially when your main competition in that field is titty streamers. And having no person on string reduce how people feel there is actually someone behind the voice.
I don't think Pippa is at the same category as pedo bait vtubers, she definitely tries to appeal to degenerate 4-channers but that's just doing smart business.
It is entirely possible to be a successful female content creator on the Internet without sex appeal. There are many high profile writers, vloggers, commentators that are women. A lot of them don't try to appeal to men at all.
Vtubers do try to have sex appeal or a girlfriend experience, they just use a cartoon character for it, which is useful because it bypasses a lot of problems the video streamers have, allows them to set a character with arbitry appearances, and fill niches that don't get filled ordinarily by other people.
Women who do create content that appeals to men always get sexualized, even the little kids. QED LtCorbis, who was drawn into porn, masturbated to by Ethan Ralph live on air, and disappeared entirely after trying to call attention to sex abuse allegations against Sam Hyde by people she knew.
Once her content stopped appealing to men, her usefulness as a content creator was extinguished. She also was cast out as a young teen, which indicates the usual lie that people like Laura Southern only start having issues with their medium and audience once they 'hit the wall and get jealous of younger women getting more attention', because they don't get much younger than Lt. Corbis by the time the adult men grew tired of her.
Pippa, rounding back to her, exists in the same stratum as Corbis. Her character has the same kind of look as Corbis. She interacts with the same people as Corbis. Her benefit is that there is a professional barrier between her and her entity, her company, which helps protect her privacy. And this privacy permits her to explore the same kind of male attention that Corbis did, more safely and successfully because she is an adult.
All that's well and good, as far as the law is concerned, and there's not much I can do about it. Just don't pretend that dressing up like a child and talking like a child and squealing like a child is some nuanced form of entertainment I just don't understand. I see what she produces and I see what she promotes. The purpose of a system is what it does.
