> Have your extensive comments about the CCP on HN caused you any hassles?
CCP currently cannot monitoring all foreign websites, so (currently) I don't think people will be hassled because of few archived comments on HM. But who knows, that may change in the future, and somebody may report you just like what people did during Cultural Revolution[0]. So, keep yourself anonymous under another name is always important.
In China, domestic websites are required by law to verify you and record your true personal identity (Phone number for example) when you trying to post anything on it, so you can't be anonymous. When I using that kind of website, I never do anything sensitive (Or even post anything useful).
