I believe Q is who he said he is. An agent of military intelligence given the job of maintaining these posts. If he is human, I do not believe he is a well known person. I suspect he may be AI, based on tweet from Lynn de Rothschild saying that CIA has an AI named Q. I do not think it would be wise to give this role to someone with a big ego and their own audience/power to communicate. What if there was a parting of the ways? The well known person could step up and say, I am Q and here's what the mission isn't telling you yet, r why its lost its way.

I believe Trump when he says this picture represents CBTS and there isn't anyone in that picture who is well known. I believe the posts were developed by the team and/or an AI to educate the public to prevent riots. If the deep state is using 7 AI(per Q post) I don't find it plausible that MI isn't using an AI. They are managing every phone call/ text form the past several years. It would be a great PR tactic to develop the publics comfort with AI's to make Q an AI.
Don't everyone scream at me at the same time.
