Many have suspected for years.

Over the years, some bans have been enacted against celebrities to prevent them from appearing in content. This is sometimes due to their bad behavior, but can also be done out of disapproval of their actions.
One of the most famous instances of a blacklisting affecting K-Pop idols involves the former members of TVXQ — Kim Jaejoong, Park Yoonchun, and Kim Junsu (also known as Xia Junsu).
In 2009, three former members of TVXQ, Jaejoong, Yoonchun, and Junsu, had their long contracts investigated, ultimately leading to the termination of their contracts after legal battles.

Following their redebut as JYJ, the trio, now a duo, promoted in other locations outside of Korea, with it suspected of being due to a blacklisting preventing them from appearing on Korean television until recently.

Recently, it seems that the blacklisting was confirmed to have happened.
Earlier this month, Lee Soo Man’s documentary, Lee Soo Man: King Of K-Pop, was added to Amazon Prime‘s online catalog.

The documentary explores Lee Soo Man’s career, including his time at SM Entertainment as founder and CEO. During one portion, the lawsuit involving the three former TVXQ members was discussed with Lee Soo Man sharing the company’s side.
After a portion explaining that the company had invested in the group and created their images, Lee Soo Man reveals that this logic led them to going to broadcasters to explain that it wasn’t fair for the three idols to appear.
Many have taken this to be a confession of blacklisting the three former members and expressed anger over this.

"we couldn't come to an agreement with the 3membrs so we told the broadcasters we’ve invested more than 5yrs into these artists, to cast these artists without our permission when it’s our concept is not fair" and some bitches still claim that SM blacklisting artists isn’t a thing
