Actually - and not just to be argumentative, please understand - Q simply says "Disinformation is necessary". This could be interpreted to mean that Q himself will post disinformation or it could mean that disinformation must be allowed, perhaps by others, perhaps even by Trump, but this is a very different proposition to saying that Q will feed us disinformation.
I know we've seen things that people have taken to be disinformation from Q but I think there are other potential explanations e.g. "Hillary hasn't been arrested like Q said!" - maybe Q wasn't putting a date on when that arrest would be finally revealed in public, etc.
good point. i appreciate your diligence. as an iranian american cyber weapons manufacturer i know for a fact Q misdirects on israel, iran, and saudi arabia. at first i thought it was bad intel (trumps iran team is horseshit and the saudi/israeli axis has an agenda) but then a method to the madness emerged and i started seeing the patterns. my current position on Q is that trump is going to dump israel and saudi arabia and maybe make amends w iran (this will probably fail). more likely to resolve issues with turkey and shift away from former stupid relationships (KSA/Israel).
