Update: At least KBS was not sneaky about this. Despite the ban from appearing on Music Bank, So Nyeo Shi Dae still managed to win the K-Chart for Gee, their first win since their comeback over Baek Ji Young and K.Will.
BoA, DBSK, etc will not be appearing on KBS Music Bank indefinitely after SM Entertainment were served with a notice from KBS this month. This apparently was because of DBSK no-show at KBS Gayo Daechuk last year.
