Great proof (from locked bread). You can expand this proof significantly (exponentially!). In fact, this conversation between POTUS and Q is the absolute KEY proof in the ENTIRE catalog of Q's authenticity (proximity to POTUS).
Let me explain:
You are showing a two-factor authentication proof. Two factor is like a web site sending you a text message of 6 digits when you try to login. You enter back into the web site the 6 digits showing on your phone proving it is you. Two parties (you & bank). Two platforms (web and text). Get it? You have proved two-factor authentication Q and Trump. 8Chan and Twatter. Get it?
In reality, Q post 453 was RESPONDING to a Trump picture tweet holding a 5 line item talking points card, while holding 5 fingers in an unusual method facing away from him - toward the cameras. Q didn't start the conversation, POTUS did.
This proof needs to actually be a THREE factor authentication, mathematically impossible to fake.
Conversation:
Trump (participant 1) holds 5 line item talking points card when school shooting kids visit WH (find pic). Item 5 on the card is something like "We hear you." He is pointing to it with his #1 finger. News cameraman (participant 2) thinks they caught POTUS exposing his talking points card and zooms in - goes out on national TV (MSM even mocks it). So participant #2 has transmitted participant #1's message on platform #1.
Q (participant #3) posts on 8chan (platform #2) - Device_1_X (Executive's first finger). Signal is 5 by 5 Read_(past tense) "I read your message clearly."
Here is my RETURN message "58 spaces"
Participant #1 (POTUS) tweets "58 spaces" on platform #3.
3 participants, 3 platforms. This is like a bank web site sending you a text message to confirm it is you logging in, then calling your spouse to make sure you have permission to move money around. 3 participants, 3 platforms. Impossible to fake.
Why am I using this "factor" term?
The reason I am using this metaphor is banks use 3-factor authentication for moving millions and billions of dollars every day via wire transfer. That's how secure it is.
While there have been numerous examples of Q and POTUS exchanging a single conversation, THIS ONE is the MOST important one proving Q's authenticity.
My Austistic explanation is too sophisticated for the expected normies coming here and I'm not sure how to put that in an info-graphic proof, but add to your excellent start with this extra leg of the conversation…..
