I know this ain't a 質問 but....

How exactly do あなた know if she's a fake?

I don't understand what you're trying to say...

I don't get how you're claiming that is proof she is a fake.

I hate that. Insecure people who steal other people's identity.
I had a friend who would ラット out people like that all the time. It almost gives あなた a sense of relief, knowing that あなた halted their little game, tricking people into believing their some "sexy エモ boy", または an extraordinarily lovely girl. Be proud of what あなた look like, あなた sick fucks.
