@Jes has summarized the claims back then:
1. Jonghyun death is not just about depression. There are more things behind the curtain such as 3 people was involved in his death and they're not idols. RanFan was also said when Jonghyun was found, he was in tied position.
2. There's an older idol with initial J.Y who is recently be a new handler in SM on 2017.
3. J.Y had many sexual partners. He's in on/off relationship with one of his bestfriend. That relationship is intense and also, he had done sexual things with a member from SHINee and that member is not Jonghyun. J.Y practicing chaos magic as well in his home besides of his image as an idol who is go to the church.
4. There are transgenders in K-pop. My opinion about this, it's highly possible that we are caught off guards at first about them.
5. These artists are taught to do occult things. They can learn without us even realized from a teacher and also, they need to worship the devil. Whether it's in their dorms or somewhere else. If they can't do it at that time, amulets will be given to them. Whether it's the accesories or something else. As long as they're doing that, they're safe. A demon could be the part of their personalities.
They can feel "worthy" when they're doing that.
6. Idols who are not "worthy" to the devil, they still got their fame but they will be harshly tortured. Some of them can't even remember their families.
7. A very popular girlgroup was involved in sexual activities and they do it also with people overseas.
8. Ex trainee from SM, Stella was out from SM because she was scared about worshipping the devil. She had sexual things a.k.a t****s*** going on with Siwon and another member from Super Junior. If I'm noÜt mistaken, it's 2 of them from Super Junior.
