OK, 3rd stab at deciphering.
What's important here is that there are two threats here, and they are connected to each other. "Post noted (VIP access)" is Q's way of saying, 'In the Q drop earlier today mentioning VIP access, both of these threats were noted one after the other.' So Q was sending a message several hours BEFORE the PA rally to bad actors, saying "We know" what they had already tried (OK threat) and would try (PA threat). Perhaps the confiscation of Q related signs at the rally was related.
Are we getting any warmer, Q?
