They shadow ban topics and comments to create an illusion of fair conversation.
They have the collective ego of being relevant but are nowhere near the level of facebook or twitter or instagram. Or even Yahoo news.
They are just an annoying little site that keeps popping up like that poop that just won't flush , that's reddit , the shit that won't flush , reddit is about as relevant as myspace.
AMA seems to be the last grasp that reddit has , and why do you need reddit for that ?
