I feel like, and even Dizzy has commented on this that a lot of these girls go into thet sort of thing hoping to roll a Dizzy-esque chat. When unfortunately the only one who ends up with a chat like that... is Dizzy.
Now of course there are outliers, Embers is relatively chill for instance. But like we've seem a similar pattern happen with what is being discussed here 99% of the time. While vtubing might be hitting the mainstream, and Phase in turn attracts more of the mainstream audience, you have to remember that even then a lot of the mainstream folk are fucking gross this day and age. So not only does Phase attract the "sector" coomers that shit up Pippas chat. They'll also get noticed by coomers that tend to shit up your average twitch thots chat. And both sides are likely to poke the streamer to see what they can get away with.
