>>3939568/jp/ was made because of the touhou spam on /a/ so those are the true natives. Later on some japanese related shit got thrown into it, like the train threads, kigurumi, onaholes etc.
Then it came idols, which was already controversial for /jp/. Later on vtubers. JP vtubers are turbonewfag territory compared to the touhoufags, even if they themselves are oldfags compared to EN vtubers and /vt/.
I don't know what the fuck has been going on in the vtuber threads in /jp/, the constant anger could be either a remnant of the hostile /jp/ era (sage goes in all fields), or some kind of /v/ infestation, or the /r9k/ subhumans mutating into purityfags.
Reminder that /r9k/ has always been laughed at. Reminder that true weeaboo (gomenasai Ken-sama, japan is superior) has always been laughed at by /a/, /jp/ and the rest of the otaku boards. You retards pretend to be oldfags but you are as much cancer as the rest.
That said, discordfags and the likes are even worse since they just come here to shit up the place for fun, since their "main culture" is not 4chan, but those other places. It's basically an ongoing raid. It was bad already with the rise of phoneposting killing most OC and now we have to deal with this.
