The only logical answer I have for why people would yellow-face themselves while rage-hacking in a new game is because there is a group intentionally agitating this issue for political purposes.
It's not like they're trying to pretend to be good. They are blatant rage hacking with the intention of letting everyone know that they're doing it. There is no logical answer for this other than agitators.
This is the easiest thing in the world to do. You ragehack in a game using a Chinese name while constantly posting in communities about how the game is filled with Chinese hackers and how they need to be region locked. Then you also post all your race-theory bullshit for how they're predisposed culturally-or-otherwise to "cheating".
And because it damages the TREATS gamers react viscerally to it. They're incredibly easy to manipulate.
I honestly respect russian and chinese cheaters for not respecting gamers in the imperial core
