>Q & POTUS need to be able to signal enough to anons to inspire belief but not enough to openly admit to the enemies who are also watching the boards that Q is really actually legit.
If Q is legit, they already know it because while they are dumb and stupid they aren't that dumb and stupid. Q wants them to know it because Q is taunting them. Taunting doesn't work if the person you are taunting doesn't know about it.
