If I don’t know or haven’t read about it, it would be a case of “ignorance is bliss”.
I agree there are exceptions. But there are times when you cannot separate their private and public lives when they obviously are/were using their “star influence” and “role model persona” to, for instance, lure young and naive students/girls/boys and “abuse” them. I’m talking about confirmed and convicted cases, not mere rumors or allegations.
I read them from Chinese sites a while ago. If you want to use machine translation, just google their Chinese names and you’ll find many articles that will interest you. Beware of fake news. There are also English sites on C-entertainment that you can read from, though there aren’t as many articles or as detailed. You also can’t use machine translation for some because the news are embedded as images.
PS:I’ll try to find a few for you.
