The show is set up so that if the contestants do anything on a given list (like access ATMs, pay for something with a known card, walking past cctv cameras etc) then the camera crew would notify the hunters. Thats how they got that intel so that they wouldnt need to use actual methods.
I dont think you can use that show as an actual example of somebody on the run. Its so far away from reality and set up to be interesting to the viewer, its just not realistic at all.
The amount of camera's in and around shopping areas is staggering. And the requirement to have a smartphone on hand is increasing every day, at least in the Netherlands.
And three passports for three different identities.
In the parent case the supposed illegal activity is associated with a device (possibly the location) and they are trying to find the identity of the person associated.
Long story short, barely anyone got anywhere. Because simply doing an ATM transaction to get the cash already triggered the signal where they were. Not to mention the amount of government owned cameras. As well as being in proximity of anyone still online.
Complete anonymity is virtually impossible, depending on the country.
