This is exactly what I was getting at, glad someone else saw that. I didn't see posting relevant credentials that are easily found through usernames containing PII to really be doxxing because it's "self-doxxing", and the fact that those credentials are relevant to the discussion.

This is the problem I have with HN moderation, they have rules that they selectively enforce but it's all built on their heuristics which they never flesh-out. Neither of us can go to a page on HN and run through a checklist to determine if content in a post will or will not be considered flaggable/bannable because it's a "closed source heuristic" if you will. There are guidelines sure, but the enforcement seems very wishy-washy and selective.
