Sure.
I have interviewed a number of members of the Hong Kong diaspora globally, not just within Canada. We have found a pattern of behaviour in which many of these Hong Kong dissidents who left Hong Kong after the 2019 protests and the 2020 crackdown experienced doxing. They also felt that they were being physically followed or had seen incidents of being physically followed.
Many of the interviewees I talked to also noted that at public-facing sites, like sites of protest, they were often getting their photos taken. They were getting threats of their photos being sent to embassies so that the embassies would have their information. Additionally, they would receive a lot of threats via texts and emails and online. There is definitely this pattern of behaviour that happens.
Many of the interviewees pointed to the fact that there is a seeping paranoia that they have to live with. This in turn seeps into the community itself. There's a lot of vetting. There are a lot of community security protocols that we take in order to safeguard ourselves, because we have felt like there is nowhere to turn. There has not been adequate support in that sense.
Additionally, a lot of advocates have taken other proactive measures, such as cutting off ties with families, loved ones or friends who continue to live in the PRC or in PRC-controlled territories.
