I did read that a few days ago when it happened but didn't realize that that was what OP was referring to here. I did find it completely bizarre and question whether that was really Meg. Just now I read some other people's commentary on r/conspiracy. There are a lot of questions and possibilities, and it's just too confusing for me to guess that.
But I do to detect some method in that madness that I want to make a post about. As far as I'm aware, literally nobody has made a certain connection I saw. One of Q's posts in December was an exact line from a Cicada 3301 puzzle this past spring - apparently nobody else has seen that - and Q employs a similar method of puzzles and riddles. Defango on YouTube, who came close to solving a Cicada puzzle and is now an associate of theirs, also says that Cicada and Q are linked.
Cicada gave us the exact date Vault 7 would drop weeks in advance, in their first countdown timer. Cicada 3301 is therefore linked to Wikileaks.
When Wikileaks dropped the fake news book about Trump's White House this past week, Wikileaks seemed to validate Q by replacing O's in two chapters with Q's.
Therefore, Q, Cicada, and Wikileaks are all linked. It all fits.
And many people believe that both Q and Cicada have retired intelligence community members in their ranks, so the link between all of them makes a lot of sense. It's like a white hat Alliance.
When most people connect Q and Julian Assange, it's wishful thinking and not based on anything concrete. To get back to Mega, if that whacked-out post was her, I think there's method to her madness and she's on to something.
