BTS Trivia : Do y'all know why BTS is not part of Idol Star Athletics Championship (ISAC) anymore?

BTS attended the sports event for 4 years from 2014 and eventually got banned. There's a funny story behind it. Since their beginning in the event in 2014, the members have up raking up medals after medals. However, the reason for the ban is speculated to be taking pictures on the set. The show had some strict protocol about maintaining the secrecy before it aired. But BTS broke those rules like a boss by posting images on twitter and eventually got banned. Ain't it funny?
