I did say likely, which is different from very certain, but here goes:

A) Per post 60, there are at most 9 people that know the whole plan. I believe Q has to be one of them. Six military generals are going to be busy with their regular job and running their part of the show. I don’t think they have time of all this posting. That leaves very few options for who Q is and I don’t think it is multiple people on that list. It is possible that there are multiple people posting stuff, but it wouldn’t be consistent style and message if it was a group of people that all didn’t know the whole plan.

B) it just doesn’t seem practical that there are a group of people all with the login throwing stuff on there. Q is with the President often, aboard the plane, behind the scenes at events, etc. it isn’t practical that is a group of people. There is one person in those situations and controlling all the posts. Sure, the Q group might send a word doc with a post (or however they do it) and the single person is reviewing and posting,

While there are multiple people that contribute the the effort, I’m 95% confident there is one Q. And maybe it’s just a difference in what we are staying and how people talk.

“Did you read the new Obama book, it was a real turd!” Sure there’s editors and contributors and ghostwriters, but we still call the author as Obama

“The chef did a great job on our meal tonight!” Sure there’s prep cooks and sous chefs and multiple people with their hands in the plate but there’s one chef that controls everything and it’s the point person.

“I went and saw Taylor Swift and I was like ‘Oh my gawd, she did such a great show!’” Clearly there’s other band members and lighting techs and sound techs and all that stuff but it’s Taylor Swift. She put on a great show she’s the point person she’s in charge of everything

And I find it likely it’s the same with Q
