So I guess it's not only a South Korean cultural thing...but also indicative of the intelligence level of Yuna's fans.
Actually...looking at the English comments, the majority of them appear to be from Asians, too.
Actually, Yu-Na fans I know are against cyberbullying Sotnikova, because they're actually aware that this would only make bad images for Yu-Na. And why would they want to do that?
Yuna should stay out of it.
I agree.
