Idea: track the upvotes/downvotes/flags of users and compare them to your upvotes/downvotes/flags (and maybe other respected users). If there are striking similarities, take a closer look. If things still look good (observe comments, submissions), you've identified at least a few potential moderators.
(Also, since I'm sure anyone commenting on the state of HN will have their account scrutinized, my first account is nearly 2 years old, and I've been looking at HN for around 3 years total.)
