AFAIK (I saw dang state this a few times in his comments) it is fine to submit duplicates to HN assuming enough time has passed (a year?). He'll even reach into the second change pool and re-submit submissions that did not gain much traction the first time around, I think. So I think your first rule isn't really something that is much enforced on HN. (Which I think is a good thing.)

I hadn't heard about the 2nd chance pool until I submitted an article and he emailed me to say he was going to 2nd chance it.

That was a really neat mod intervention I wasn't expecting but really appreciated.

That's in the FAQ: "If a story has not had significant attention in the last year or so, a small number of reposts is ok. Otherwise we bury reposts as duplicates." https://news.ycombinator.com/newsfaq.html

It’s more of a guideline than an ironclad rule, though. Two different sources might have different takes on the same thing and it is not rare to have more than one story about the same subject on the front page, for good reasons. The community (and the mods) seem to be very effective at filtering real duplicates.

Another case where looking through dang's moderation comments is helpful.

The duplicates-detection code is deliberately porous: <>>7650172 >

But overwhelming the front page with multiple takes on a story (e.g., the Tver aircraft downing yesterday) would be tiresome, and even multiple takes on what's essentially the same story over a span of a few days or weeks can get tedious.

The critical qualifying exception is "significant new information": <>>8406835 >
