I automatically and completely distrust any vtuber who is openly advertising an affiliation or overt interest in imageboard culture. I don't mean 'old 4chan' vtubers like Marimari_en who are content to hint and nudge but not overtly flirt with the boards, but the kind of vtuber who purposefully tailors their image to appeal to that audience and encourages them to be parasocial towards her. It's all an act; they're not real 'girlfailures', they're not really interested in the boards, they don't want you to help them get worse. They're the 2020's equivalent to fake gamer girls. Don't give them any attention or try to help them. At best, just watch and laugh when they get exposed like Gumpai did.
