I mean, so is Reddit. Subreddit moderators are public information. All the original image did was take this data and aggregate it onto one chart. HN doesn't say "100% of posts are moderated by the same people" anywhere on the site in the same way that Reddit doesn't say "our top 100 are mostly moderated by 5 people."
