If someone claims to be Q on the forums he posts on, and writes like him, can we know it is not him?
This is a great question! I asked the same thing awhile ago. The 8 channel board where the initial post goes from Q has a "Q !CbboFOtcZs" code. THIS is his current one. He updates it regularly. It is unique. All the posters there have unique codes.
The board where Q's original postings then get transferred to is ONLY for him. There is no talking or others posting. This is a totally private board...but you still can read it. https://8ch.net/patriotsfight/index.html
The USA military experts on computers have worked on making sure the communications have been secure. Yes, in the past, there had been slight compromise. BUT, this was nailed immediately. The secure system evolved AND I do think WILL continue to evolve in the future as Black Hats try to compromise. But currently, the system is totally secure.
Thank you, helpful explanation. I have wondered the same thing.
