If they're able to dox members of this forum, I doubt they'll discriminate by nationality. But would they really have the energy and resources to send lists of names to all countries? They'll probably just focus on the brits.
But then again, it's never a bad idea to have strict privacy protocols in place. Don't post anything that could be directly linked back to you. Be careful when sharing files and images as they may have identifying metadata (use an EXIF remover of pics and download files as pdfs). Use Tor or a VPN to stay safe from your ISP's prying eyes. Use Brave as a browser as it blocks cookies and ads. Don't use Google to search for this site, use DuckDuckGo.
Also, don't mention this site your family. If you CTB, remove all traces of you ever being here.
That's the advice I can give you as someone who has been interested in online privacy and cybersecurity for years.
