Which makes me to wonder what is the logic for checking a duplicate? I know that dups are checked while submitting a link, but how far in time does it go?
If the check is time bound is it due to performance or is it due to belief that after sufficient time gap content inside an identical link could be different?
This thread gives some idea about the complexity, but still I'm none the wiser.
When I post "related" links like in https://news.ycombinator.com/item?id=32135274, the purpose is simply to point readers to other discussions they may find interesting. It's not meant to imply "these are dupes that shouldn't have been reposted". I hope that's clear!
