he looks the same in every vid because it's an invented persona, it wasn't the real him, just like actors like hugh jackman, people think he's a ladies man and a tough guy, hell no he's fruity actor. even has a beard to go along with it, not talking about the one on his face
the zyzz kid is not so much a fraud but just another actor. in my experience, people who are long term addicts of cocaine have a psychological addiction rather than a biological addiction. they snort cocaine because cocaine allows them to live out their fantasies, allows them to live in a fantasy world, it dulls the pain of living a lie - alcohol does the same thing for some people
zyzz played the part of narcissistc beautiful boy who everyone wanted to be, it wasn't really him, he wasn't really arrogant. it was a part he played, the real zyzz was a gentle guy, i assume probably bisexual or gay, and i like him
