If Q is real, then the black hats have seen enough in his posts to know that he is real. Therefore, if he is real, and he posts something, they are reading it and it lets them know the same things that we glean from it. If Q is real, then he has to understand that the bad guys know every bit of information he is giving us, and they are ok with that. Some of the things said might be better kept secret, unless there is something we don’t know.
