This seems to be a common misunderstanding. Admins and moderators have no different powers than anyone else. I (not an admin and not a moderator) can collapse answers with "improvements needed" any day of the week. So can most anyone else. It takes a special kind of person and insults being flung to become edit-blocked, something that happened to my knowledge and according to Bodnick less than ten times in the history of Quora. The author of the linked piece was one of those people because, alas, she could not be asked to act like a reasonable human among reasonable humans, that is treat everyone as an equal and debate on the merits, not the perception of standing.
Promotion of views is the same. Spend six months on Quora and establish yourself as a knowledgeable person in one area (see: Michelin chef Jonas M Luster in food or former police officer Justin Freeman in law enforcement) and you will have credits to promote content, including your own. Your standing in answers is based on votes, your power to elicit answers or promote questions is also based on it. Nothing that does not happen anywhere else. No one on Quora becomes a "superuser" over night, those who spent months giving insightful answers all have.
