https://github.com/minimaxir/hacker-news-undocumented/blob/m... has some details on flagging and vouching. Your account is below 31 karma so you don't see the links/features in the user interface yet. Besides users there's only two people working on HN. https://www.ycombinator.com/people/ lists only one, but I see somebody posted the New Yorker article that includes the second moderator.
