Any disease severe enough to present symptoms maybe trivially tracked in real time by key words used in searches. It is possible make differential diagnosis between similar and dissimilar disease, by tracking numerical identities we can see the course and severity of the disease, plot outcomes. If the outcomes change and the disease indicated by symptom searches remains the same we may infer what?
Who has access to such data?
Could keyword searches and social media filters let us track other topics and trends?
What would backsearch tells us about the first use and subsequent spread of cult sponsored phrases, slogans and ideology?
Could we take assertions concerning events now acknowledged to be true; "Obama spied on Trump"
identify the first assertion "Obama did not spy on Trump" and track the dissemination over time, and so construct a proven "liars network map" that can be played backward and forward in time.
Who has that data? Cable carriers Telcos, ISPs, nation state intel services, search engine operators, Big Tech, Apple, Googler, FB, many more.
Who can buy access to data from Apple, FB, Google, Twitter etc?
This data is generally called "meta data" and it is always said to be "stripped of personal identifiers" per cultist drone MSM media.
Howevah in the event a customer did want to discover real world identities of anonymous users, that's easy to do by localizing keywords.
In truth, having the 'meta data' is having everything.
We know what the data can be used for; what it is being used for is, at least for the moment, is obscured by the stinking clouds of digital smoke being pumped by cultist media on every pedovore platforms.
