FYI, there's an interesting commentator machine operating in China for public manipulation https://en.wikipedia.org/wiki/50_Cent_Party I'm not ruling out genuine believer of their opinions but there's also this possibility. They're getting pretty sophisticated and sometimes instead of supporting the government, their goal would be disinformation, induce hatred (i.e. troll) to divide and conquer. If you're interested…
Of course whenever anyone writes anything pro-China on the internet, people are going to assume it's the 50c party, just like I assume anything pro-Microsoft here comes from a paid shill or a bot ;)
