The only real question I have is why would Jan/Jace continue this massive charade for years despise being relatively obsucre, because he's just only recently these past year and a half got a sizable audience. I remember for most of Jace's time on the internet most of his videos only got a few hundred and maybe thousand views with the exception of a few like the the Hater's Hit List and the Dating advice videos which went viral. It was just really only recent that he his videos started breaking the multi thousand view mark, so why would he stick to this for so long when in the beginning barely anyone was paying attention to him.
For now I'm mostly going to wait until Jace says something about this or Jan finally breaks character and come out gives an explanation.
