Basic op sec.
Okay, Dr Sinister.
Who is twitter guy?
What does he do when he's not twittering?
Is it possible that, like Q, there are others behind the tweets issuing instructions?
You don't have enough information to make that call. What you do have is a tweet calling Biden the 'former democrat nominee', which they almost immediately deleted.
My basic opsec says maybe it wasn't an editing error and that it may have been a 'slip'.
Furthermore, my humungous brain tells me that knowledge of OPERATION REPLACE BIDEN (if it exists) may be more widely known by media derps than we would normally think. After all, they are the ones tasked with setting the stage, or plowing the field, if you will. They must write the stories and tweets that set up the operation.
Also that 'twitter guy' may have other duties than twatting.
