Also you can't deny that the jokes (rizz, getting bitches, etc.) are jokes speifically used by Gen Z and are new trends, this game feels like its trying to be hip with the kids and Vtubers as a concept are very popular among teenagers as well.
They can be but that would not be the reason really why i would assume that she is trying to be hip with the kids lol that's a bit of a reach older Gen Z or people that are millennials are into that too you probably are more around to those in your age range but it's really common and Vtuber are not that new of a concept really same with that slang lol. But again i won't deny that teenagers aren't here in the comments but it's mostly from youtube videos of people with a younger audience
Again agree on the other points but to me there a quite a lot of adult in her community. The comments here are not a reflection of that more so people who follow her on social media.
