I don't think it's fair to vtubers with loli models to act like they're all pedobait. I've watched girls like
Ami Amani and
Zeli Zuimu on and off since their debuts and I've never noticed this kind of stuff from them, they just happen to be lolis, and so might get a stray sob emoji or two, but otherwise go about their content perfectly normally. Muu's chat is the way it is because she actively encouraged it as Purin.
