generally it's a mix of the "fans", the faggots in the community who love the lolicon shit (Pando fans, MariMari fans, that one disgusting niglet who was literally a 5 year old fans, etc.) And then the people who hate Vtubing so much, they radiate autism.
The reason I'm no fan of the guys who hate vtubers to the autistic degree is purely because they make it much harder to actually document shit that happens because they're too busy shitting up the thread with the same shit that anybody who is right in the mind should agree with (total Pedo Death). If we could have 500+ pages of information regarding the shitbags of Vtubers, all documented perfectly so that it could provide good posterity, then it's perfect. But instead you end up with 500 extra pages of niggers sucking the cocks of Vtubers being documented, and an extra 200 pages of tards who already hate Anime and Vtubers coming into the thread and derailing the entire thread.
Great example is Pippa. She's had like 4-5 threads made of her. All of them are dogshit because the OP is running gayops and using slop rrats that may not even be true as factual 100% evidence. There's a massive difference between a rrat (ie. "Mikeneko touched kids! Don't you see? She clearly dresses like a loli!") And something hypothesized with tangible evidence (Like Mikeneko going to Japanese Keemstar and with screenshots).
It's something that gets lost ultimately because of the cancer surrounding Vtubers and Anime.
