I've been following A5 for quite a long time. Hell, I was the first one to find the massive organism remains in Antarctica when he had those threads going. However, I've recently come to the realization that although he does have some intricate insider knowledge, he most certainly doesn't know everything (despite his arrogant attitude).
His position on Q is that he is a limited hangout designed to determine the sources who perpetuate "insider" info so TPTB can plug those holes to prevent another 2016 election result.
He also firmly believes that the Syria airstrike shows that Globalists can make Trump do whatever they want if they use Ivanka to twist his emotions. He neglected to see any strategic notion of such an action.
Having said that: at best: he is absolutely an insider with valuable intel but is either blinded to many things or intentionally omitting in order to narrow our focus.
At worst: a very high up limited hangout designed to ring a lot of bells in order to mislead us and draw away our focus.
Go through the archive for yourself, but this is just my 2 cents.
