so. many.
boys' planet: haruto. park hanbin (i feel like being a namesake of a more popular contestant doesn't help things). kuanjui. keita. woongki. sungmin. jongwoo - the hate train towards this man during the course of this show was absolutely horrific and absolutely uncalled for. all the evil-edited trainees - krystian, jingxiang, shuaibo too (okay fine let's be real, i along with most people don't necessarily consider the latter two talented, but they did deserve better).
now as you said "people" in the title i'l say... what if these people we're talking about are NOT viewers and voters. but the producers who were involved in vote manipulation? they're people too, right? hence i say: kang dongho, lee kaeun, and han chowon. lee haein too. and these are just the names i recall as of now, there's tons more.
