STAY AWAY FROM YOUTUBE. Exploits have been taken further to now steal account details.
I HIGHLY recommend staying away from youtube for the time being. The exploit involves javascript which can be used to give your computer a shit time via browser exploits (this applies for all browsers). Watch youtube videos at your own risk.

Anyone can inject code to youtube videos
