If anons can't spot an "unmarked Q post" by now, they haven't been trying. 2,070 post-number delta from prior (27-JFK), 1:28:23 time delta (←17, 2… →28:23-JR, P@in), 19's and '11:11's in both time and post # (6+5=11)… you get the idea.
TRUST KANSAS (KS)… he's been undercover for a long time, from what I gather.
