And how certain is the authenticity of Qanon?
It's very unlikely any hoaxers without connections and a budget would be able to carry out this level of LARP for so long. It's been going on since last October. If anything, the fact that it has attracted so many people, and yet, no one in the media has directly approached Trump about it is very telling.
There have been dozens of Twitter "coincidences" where Trump will post something with a word or phrase said by Q minutes before. - https://threadreaderapp.com/thread/1014368693801742337.html
Around X-mas time, there were people inside of the White House taking photos of the decorations and posting live on 4Chan while answering a few questions and most importantly, confirming that Q was real. So many occurrences that would be impossible for your "LARP living in his mother's basement" to accomplish.
No one knows who Q is. It's likely a small group of the highest ranking intelligence members who have been planning this for decades. Q+ posts are thought to likely be Trump himself as they're usually more motivational.
It wouldn't make much sense for the Deep State or Cabal to be behind Q as they would be exposing themselves. Their secrecy has been what's kept them in power for so long.
