On June 22, Yubin wrote on her Instagram, "I'm angry after discovering something odd while on the internet tonight. I have no memory of 'unfollowing' anyone so the fact that something I have no memory of has happened is something ghosts would cry about. I'd like for something like this to never happen again. I hope that no unnecessary misunderstandings come from those I supposedly unfollowed. And if someone by chance has hacked into my account, I would like for it to never happen again."
It seems like Yubin is pretty fed up to have her personal SNS accounts exploited. The post has since been deleted from her account.
