I'll say not to my satisfaction. It was kind of discussed as an already decided piece of info. Without knowing the history myself, I googled the story about it in the doc, and from that I'm not satisfied with the explanation he gave, that Walkins' comments were a wink and a nod to him being Q.

In the article I read, they talked about maybe one person managing Q when it was on 4Chan, and possibly another when it went to 8kun.

I could believe Bannon was managing it at first with the support for Sessions, and others later on. Someone like Bannon running it would also fit with how some things didn't pan out, as MAGA was edged out a bit many places by traitors. Take that as an outsiders view with limited insight.
