of navalny, and those were suspicious, but once we have a suspicious number, you go through a number of russian apps that allow you to see how that phone number is listed in other people's phone books, so, for example, i put in my number, and it would show up as kristol the journalist from bellingcat because somebody would have put my name into their phone book and that description would be shared. first number i showed up alexei, doctor from fsb. that was interesting, doctor from fsb,alexey. couldn't place a real person behind this name and looked to see if that number shows up in a car registration. that a le xey owns a car and then you have a real person with his birthday, look up his passport file and see his face and you repeat that many times
