Fans who have already been following him can still see all his posts, but they can no longer reblog or embed his posts (as is standard of locked accounts). New followers will also need to be approved by Daehyun himself, meaning theoretically, no haters can see his posts.

This follows the upset posts on his account on reports of a substitute during B.A.P's "Hands Up" MV. 

  

Hopefully everything will work out for Daehyun.
