Its cause it's better to be unique different and rare like Q then common everyday part of select few required to be in all things like the letter E or vowels. Only Q can hide behind a simple letter. Anyone else needs at least a name or fake name in order to be taken as anything more than a fan with a theory. U either Have a theory and are willing to stand with ur name behind it and if ur wrong move on or u provide provable info about things in past and hide behind a letter. U cant tell stories of future things and be anonymous.
