>>575258Years ago, Nyanners was a /b/tard or general 4chan denizen who did voice work for manga, usually doujinshi, and was a general memelord shitposter like the rest of 4chan at the time. I say "at the time" because the 4chan of today doesn't even come close to resemble those old days anymore, but I digress. Being the memelord that she is she eventually did a parody song done to
https://youtu.be/M9XbJxKSTlk changing the lyrics to match a particularly notorious loli doujinshi and some of the memes that sprang from that notoriety called "PomfPomfPomf" which you can still find on YouTube if you look. The details after this get a bit murky because some people say that the response she got from that scared the shit out of her because it got taken in a way she didn't intend to she just went full SJW. Regardless of what is true, it is a fact that she publicly denounced the response to that song and declared that loli was gross and akin to pedophilia and she deleted that video and a lot of her old content (keep in mind she was in middle school when she made all this). There was also some stuff about people pissing on her dead sister's grave, but whether that happened before or after Pomf I don't know. Anyway, Nyanners mostly distanced herself from that old content and went relatively obscure for a few years until she started coming back making more shitposting content and this year became a vtuber and later joined VShojo, keeping up a lot of the kinds of things she used to do in the past, but not quite in the same fashion. She does a lot of meme stuff and shitposting, but doesn't do anything associated with loli or more hardcore aspects of old 4chan culture. She still makes use of a lot of 4chan memes, especially old ones that most people these days don't even remember, and has become even more popular and successful than she ever had been before getting 1m subs on YouTube this year and becoming one of the most successful Twitch vtubers.
That's about all I know that is solidly backed. The antis love to spout a bunch of other shit that has no basis in fact and is just opinion, and there's a ton of exaggeration and outright making shit up that goes on. It's hard to keep track of it all. Anyway, that's the long and short of it.
