Nuking her discord to join is quite the flag to string up at the onset. If I were already emotionally invested, I can't say that's a move that would instill me with confidence.
Vtuber discords are a magnet for parasocialism that goes both ways. Nothing stops these people making a fan discord. It's better that way, because then the talent can disavow the actions taken by its members instead of being automatically responsible for everything that happens there in the eyes of the public. The fewer chances a creature like SOTI or Spooki have to try and worm their way into a vtuber's good graces, the better.
Even the literal whorecorpo Vallure decided not to have an official Discord. The women who objectively benefit from having parasocial fans decided it was a bad idea. More vtubers should learn from their example, and it disturbs me to have to say that.
