OG methods

1. Newspaper articles/headlines
2. Newspaper crosswords.

These are still used today but technological advances have created a myriad of forms of encryption.

The DS has been shown to use

1. Huwei phones, a special order backdoor batch that was intercepted.
2. Gaming Comm channels like Discord. Private chatrooms.
3. Tweet headlines and comms.
4. Hollywood everything

As for book comms......your idea is very interesting and is probably practiced in one form or another.

Cryptically speaking, the worth and expertise of a director is often gauged by his ability play to both his 'team' and the peanut gallery. How to make an important point or brag without tipping the secret.

A red-pilled OG always watched a 'different' movie than the normie.

Go watch some of them again. Dial 'M' for Murder.

The secret to control contains the creation of opposite extremes to play against each other aka 'Zeno's Paradox' or it's modern imitator, the Hegelian Dialectic.

Playing 'black vs white'.....Hollywood made a killing on the dialectic didn't they? Literal white and black characters......all the while promoting '50 shades of gray' just to muddy things completely.

There is an actual test of a would-be director applicant for his ability to convey this. This itself, is a secret 'comm' between the applicant and the tester.

The name of this is "Coffee and Cigarettes". (black and white)

Feed that title into YouTube, and note who is shown....and the subject value. (There is a skeleton 'plot' made available to the applicant.....but they are expected to provide detail as proof of worth). The actors may or may not be 'aware' of the secret comm going on. It becomes a test of their own understanding and ability to improvise.)
