The conspiracy people who post on Facebook are the ones that make me laugh, they'll post about shit like 5g and Bill Gates microchips.....on Facebook...while posting what they ate that day....no one needs to track you secretly when you post literally your every minute of your life.
Yeah, this was an actual secret conspiracy for over 20 years, though. This is an example of a real collusion between global governments and corporations to track members of the public.
So the yellow dots became public knowledge 20 years ago, and other than a one liner that other tracking methods may exist, nothing about these other methods seems to be published. Surely the three letter agencies haven’t given up on tracking.
That is my understanding. And I assume the dot patterns are made by printers worldwide. The article mentions Dutch law enforcement using them, and German researchers studying them.
