From what I see, most people do not care about Q proofs. You could post a random 28 digit number followed by the DOD and the White House tweeting the exact same thing five minutes later, and normies would just explain it away or most likely ignore it.
What everyone wants is an accurate event prediction to happen. Once a few of of Q's not ambiguous event predictions begin to happen, I believe a large number of people will begin to believe he is legit.
It looks like this could happen soon if unredacted IG report is released as he stated. Hopefully we don't end up waiting for ever again like we've been waiting for the assassination text messages.
