There really needs to be Online Transparency and Recourse legislation that forces companies to offer:

1) A clear explanation for whatever violation has caused them to block or remove something.

2) A means to remedy the issue

3) A means to appeal the decision

WIthout these we are literally living in Communist China. Its not much different than Jack Ma mysteriously disappearing from the planet with no explanation. Someone didn't like something and like a bolt of lightening from the heavens, their problem goes away.
