If you dig into this person’s posting history and also if you read regularly on HN for a couple years you will notice that it is actually this very user that deliberately uses the 0 prefixed 5 digit year numbers, and also goes out of their way to include year numbers into their posts to make people ask this question.

Hmm, I checked the last two pages of their history and this is the only comment with a year, so it can't be that out of their way.

I'm puzzled about what sorts of discussions of historical coinage policies lynguist is used to reading that don't mention specific years.
