twitch pulled out of Korea due to the amount of money they had to pay up and thought "Nah, too much money and the return aint that huge to be paying that much".
kpop trial thing where they were like having the idols flash and enter the sex industry
i dont even know where you heard them but im sure those are the shady ones and not the actual Kpop industry. Also Twitch closed down due to financial issues (they had to pay too much tax or smthing)
