There's a much stronger correlation: these accounts (plus a couple others—who are also active in this thread) all comment about one highly specific, niche topic which absolutely no one else on HN does. It's the claim that the Bush-era NASA Administrator, Mike Griffin, is a unrecognized key figure behind SpaceX' founding. Just query "spacex mike griffin", and it's exactly these accounts (and people who reply to them). https://hn.algolia.com/?query=spacex%20mike%20griffin&type=comment&sort=byDate&dateRange=all https://hn.algolia.com/?query=spacex%20mike%20griffin&type=c...
