You got a big BOOM for 4000 :)
I recall now, almost ancient history in Q terms, that there was speculation that they were communicating through games, and we saw several images of people in congressional meetings, etc., playing games. What they were really doing, it seems, is communicating.
Now, if the game(s) they’re using are known, It would stand to reason that the comms were NOT hidden at all, and were being watched by the good guys.
I should ask more often.
