VTubers are streamers who use the advantages of their appearance to do things you can't do while being completely yourself, like having fanarts, doing anime acts without feeling cringy, basically being somewhere between a streamer, a fictional character and a voice actor. From this point it completely depends on the creator
>>3546171>Attracting mentally ill desperate lonely men is Hololive's fault>Attracting alcoholics is a bottle of vodka's faultStop projecting lol. While I believe lonely men is a main audience there is nothing wrong with it, as busy men or women who don't have enough time for socializing or who spent years when they had to learn to talk to people to study is not a rare sight nowadays.
Loneliness of course is bugging, so they watch cute girls to not feel alone during evenings and keeping the healthy limits, just like with the alcohol.
Spend more time in places like 4chan, be nothing but a lonely schizo and wonder why you are surrounded by mentally ill social outcasts.
