According to Seoul Metropolitan Police Agency on October 1, their cyber crime unit carried out separate search and seizures at the headquarters of STARSHIP Entertainment, MBK Entertainment, and Woollim Entertainment.

X1, the final debut group of 'Produce X 101', contains Song Hyeong Jun and Kang Min Hee from STARSHIP Entertainment, Lee Han Gyul and Nam Do Hyon from MBK Entertainment, and Cha Jun Ho from Woollim Entertainment.

Mnet's survival audition program 'Produce X 101' is currently under investigation for vote rigging suspicions after fans discovered a pattern among the final vote results, which was statistically impossible.
Suspicions have been brought up for the previous audition programs of Mnet―including 'Idol School' (2017), and 'Produce 48' (2018).
