Juan is very good at what he does. There is a reason why he keeps this character from being known. He is well studied on the Q posts which leave many believing he is Admiral Rogers and therefore maybe Q.
Alternatively, if Admiral Rogers or Q did want to disseminate information outside this platform he would be smart enough to not only conceal his identify but would also be smart enough to pepper this board and social media with disinformation about his identity.
Don't matter either way - we are at the precipice right!
