Here's your medal for being the 2000th person to shit talk a group of people you can't speak the language of or have ever interacted with outside of watching anime and Vtubers. If you think scapegoating Idol Otaku over and over is going to work then you might want to look at some of their recent collabs with Holostars that actually happened and tell me if this band of evil Japanese men are as pervasive as you think they are(Matsuri and Rikka are well-liked and collabed just last month). A few bad apples can't be controlled and that's exactly what happens in ever incident. But don't let that stop you from painting the entire community the same way just to confirm the rumors you heard. I'm sure you'll be able to go read the Japanese comments and confirm.
