It has been my understanding that all that’s necessary is a connection electrons can travel over; bots can access etc.
Not sure that a piece of paper puts out electrons to a connector for bots to access, at least not before by some means it is even made available to a connector.
Q can doubtless keep their evidence outside of surveillance capabilities, protect evidence and as necessary, block electrons. But, what do I know of NSA’s abilities and controls, on the cusp of 2021.
