Come on people, we need to think of a plan to eliminate her.
I say this:
Create a fake TV personality, as in, find a person who will act like another person who has obviously major issues (but is not a real person). Once we sneak this new person in the news he/she should become ridiculously famous for his or her problems.
Once our new personality is famous enough, have him/her set up a lunch meeting with Hannah Montana, and repeat until our personality made such a large impact on her that she makes a worldwide statement about how worried she is about our personality.
Now's the cool part!
A group of people (en league with the fake personality person) exposes the fakeness of the new person - the group should remove all evidence that he/she ever exsisted, and tell the media that the personality only ever exsisted on the screen, and not in real life.
But if the person never exsisted outside of the TV, how did Hannah Montana see him/her? She's a liar!
See what happened here?
Granted, it would be our word against hers, but she would still draw tons of negative flak and mental distabability rumours.
However, I know no one on NG (including me) would have the guts to organize such a stunt.
