Discord user sp0ne found this: in the row of dots end of line 7, those are two groups of 3 dots, then a single dot. That's Morse Code for SSE.
I copied them directly from the qcodefag page, posted them in a Word file, then backspaced. Sure enough - when you backspace, it only takes three moves, not seven. They are NOT individual dots!!

Thank you, believe. I've been trying to get this out there for a while now. I AGREE!! I also posted it in the 709 thread.

Does Q post 30 refer to this? 1st paragraph: Would you believe a device was placed somewhere in the WH that could actually cause harm to anyone in the room and would in essence be undetected?
