Today in 2018, Q posted #1706: u/#q1706
In my opinion, one of the best Q proofs we've seen. Q states No Name will be returning to the news, and one month later, to the minute, even accounting for time zone differences, he dies.
A fascinating proof that Q is connected to military operations and absolutely knows and controls what is going on.
(If the times don't add up for you, remember Q posts in EDT, and Arizona doesn't celebrate DST, so they were 3 hours behind DC the summer this was posted.)
This was the best Q 'proof' of all time. This is the one that convinced me.
The probability of this one being a coincidence was infinitesimal.
