I think the answer to that is that so many Q "drops" come out after the events they claim to predict. Also, the links between the events and the resultant Q drops are 9th grade English teacher levels of "subtext" at best and downright spurious at worst.

I hope this isn't interpreted as dooming as I truly want to believe, but sometimes the gulf between what I want to believe and what there's empirical evidence for is too great for my own suspension of disbelief.
