That may mean you've been slowbanned from HN. If you slightly annoy a moderator around here they'll flag your account so you see very long page load delays.
Try logging out of HN, and see if the long pauses go away for you.
Nope, no list of moderators. You'll never know who, and you'll never know why, and you probably won't be able to get it reversed.
Also, Macro: The step beyond slowbanning is hellbanning, where nobody can see your comments except you, and users with "show dead" on. You've been hellbanned for over a year. As to why...maybe some mod thought your first comment was a bit content free. Maybe they were just having a bad day. I'd recommend getting a new account.
