Belarusians that had to flee the country after August, 2020 set up a whole website where they meticulously map all those involved in stealing elections and beating protestors, see http://blackmap.org/
They even publish addresses of people who deliberately reported protestors to the authorities, together with the report summaries.
In a society run by bandits, violating privacy to expose their deeds is not even a lesser evil but a moral obligation.
Also, how is the work of Brian different from the work of Bellingcat or Navalny Team? Both are prased by media. So is Brian.
I have an answer: Privacy is a luxury, not a right. In peaceful times an democratic societies everyone can have some privacy.
When people starve to death, get beaten or killed while others amass riches, privacy means little in the face of defiance, hate and revenge.
