HAHA!
Everyone has the ability to hack just as everybody has the ability to go out and get a super fancy mouse. Doesn't make the mouse any less cheating. Both give unwanted advantages over someone, but someone's hardware is something no one can control and thus, is legal. That being said, I don't think she's a cheat, she just seems to be very good. I for one can't aford a mouse, or even a computer to run minecraft over 15 FPS. So, sorry folks, I'm not gonna be a star at PVP any time soon.
Well, not till I get improve chat working.
