I'd be amazed if at this point the CCP hasn't figured out it can have a lot of influence over the western intellectual class just by running tons of clandestine HN accounts. If people are that concerned about Russian hacking, why not Chinese when it's even more in their best interest?

You can always not-go to china, and their social score doesn't affect you at all.

If you're american, facebooks(twitters,googles,...) social score can affect you pretty much immediately.
