Actually you may be right. There are many instances, like SerpentZA's parents being harassed in their home country (https://podcasts.apple.com/us/podcast/the-i-hung-up-on-warre...) or student from Hong Kong being doxxed and harassed in US (https://www.boston.com/news/local-news/2019/05/28/frances-hu...) that are obviously done by people sympathizing with CCP but without an obvious direct participation of Chinese government. Although keep in mind that if they are doing this it is a consequence of their government's policy encouraging this behavior.
