Yes this website keeps popping up in HN.
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?

- achow 4y agoThanks. This thread gives some idea about the complexity, but still I'm none the wiser. https://news.ycombinator.com/item?id=23206417 https://news.ycombinator.com/item?id=23206417
- dang 4y agoThe main thing to know is that reposts are fine after a year or so. pvg has already pointed this out but it's worth emphasizing. When I post "related" links like in https://news.ycombinator.com/item?id=32135274 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!
- pvg 4y agoThe two important things are that duplicates are ok after about a year and most other duplicates get caught by users and moderators if they get past simpler checks. So fundamentally the technical problem of dupe detection is not all that important to the site. There's some annoyance for submitters who feel they miss out on their rightful karma when their submission of something doesn't get traction but I guess they are a small magnanimous fraction of all users.
