I’d like to understand how this works.

This account was created only 13 days ago.

It has made only one submission, which is this post, and had only two comments before submitting it.

How does this happen?

I have an HN account that is 10 years old, but when I submit something, it often gets flagged almost immediately. So how exactly does HN’s flagging and ranking system work? Does account age or karma matter at all?

For reference:
