It's not considered a repost unless it has already gotten attention recently. Things like time of day or day of the week or just randomness can affect if a post gets the discussion is deserves, so HN does allow reposts.

From the HN FAQ[1]:

> Are reposts ok?

> 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.

> Please don't delete and repost the same story. Deletion is for things that shouldn't have been submitted in the first place.

That doesn’t really answer the question.

Often I submit a link, but it doesn’t even get a submission made. Instead it just counts as an upvote on the same link that somebody else already submitted.

I’m guessing there’s a time-based cutoff.

It's something like 2 days iirc.
