How lol? 6th Sense allows reactions and even allows lyric videos. You can find many for Uni5, but st319 blocks everything.
UNI5 pre-new members did insert english subs on their mv's, but now they disabled that function. At least they allow people to react to their videos. ST.319 are doing the opposite, and they clearly copy a little of 6thSense strategy.
My hope for VPOP to getting a little more known outside of Vietnam is diminishing, but oh well.
