A lot of us don't do the TLDR thing. That likely isn't a term a New York Times Best Selling Author who manages to read QAnon posts is likely to say either.
Though after he responded to that saying he'd need help and tutorials what we hit him with might have been too much then, but really I know he joined Gab. I guess Gab is doing Gab TV as well. Also, it was around that time that youtube began back pedaling and saying they made a mistake, blaming it on the algorithm, blaming it on volunteers, etc. Dr. Corsi was specifically listed in some of that so he is at the eye of the Hurricane I think.
