Guess I don't think it's that bad because she's not underage where I live. Also, the industry that she is in (along with every other K-pop Idol) is a tough one if your wanting to experience anything sex related (which is normal at that age obviously), and that's why you may get people that would go to the extent of cybering or whatever, though I'm sure they wouldn't have their faces shown!
Which is another reason why I think this isn't her, do you think someone would risk their career by showing their face on cam while stripping? I think she would be smart enough to at least not have the camera pointing at her face. And I could open up photoshop and draw a couple of dots on a picture in a matter of seconds and say it was her, then post it all over the net. Something like this can never really get proven unfortunately, we'll just have to wait and see what actions her management take.
