This has never been a significant barrier for savvy Chinese to post outside the Great Firewall.

International Steam is also banned in China yet we curiously see the majority of users nowadays use simplified Chinese.

and no chinese nationals work in the US. oh wait yes they do. and in my experience the majority plan to return to china after making enough money.
