It seems to me you're making a lot of assumptions and jumping to conclusions. How do you know these trolls are adults and not angsty teens? How do you know it's not a niche problem (I've only ever seen this cringe behavior in low-effort FPS like CoD)?

Not saying you're wrong but your experiences don't match my own. I'm open to having my mind changed but the idea of some conspiracy to influence kids by screaming naziisms at them at the end of video game matches just seems... hilariously ineffective.
