It finally happened. After years of warning from researchers, journalists, and even governments, someone used highly sensitive location data from a smartphone app to track and publicly harass a specific person.

NYT used location data to track a specific named "Capitol rioter" who had at that time not been charged with anything, even giving away where he lived.

A Twitter user harvested location data from Parler to track "Capitol rioters".

This isn't the first time it has happened. It's the first time they care about.
