Gotta keep your model game strong
It's easier for Chinese people to watch "banned" US media than it is for Americans to watch Chinese media from within freedom land.
Remember: you're not allowed to criticise countries that apparently have freedom of speech.
Personally, I think she shouldn't be on YouTube for a completely different reason. The internet is actually unsafe for children that young and there are a lot of disgusting pervs on YouTube. You're not supposed to be on social media till you're 13, and I think even that is too young, a safer age is probably 15 or 16.
And as we've seen here, if you're from a country the west hates, you're a target. Even if you're a child. Not against people in the DPRK posting to YouTube, obviously, but for their safety it should be limited to full adults only.
