Basically any GFE vtuber that panders to unicorns. We all know that they're mentally ill, sharing the same disease as Incels and Borderline abusive partners (seeing another male just talking to their oshi makes them berserk) so of course the most vicious and manipulative of vtubers will be the ones willing to exploit and monopolise them.
It's ironically the vtubers willing to cooperate and collab with men that are the least manipulative. It's just making friend, right? That';s called normal human behaviour. But in the mind of a schizo incel unicorn, that means he's being cucked. So they will gravitate to the GFE vtubers - which, again in irony, are the most manipulative amongst vtubers.
