Every video posted to tiktok is run through a AI supercomputer al gore rhythm to look for things like :

~products made in china on person and in background
~preferences in political policy
~angry facial expressions and what that person is talkin bout to upset them
~average agility of population ie. strength, balance etc.

the list goes on and on. The videos are geotagged with the location and time of the poster, and cross referenced to link that user data with the main spy database containing other stolen data such as credit scores, occupation and military training.

The supercomputer is able to give relevant data because it filters through billions of videos and can draw conclusive information which is also of military value.

tiktok is a virtual live cam of every part of america for the CCP, they don't need spy sats or spys because americans are freely giving the CCP their private information, which en mass is very telling of a populations social, geopolitical and physical health positions.
