It’s automated if you submit a link which has already been submitted in the last (I think?) 12 hours, it just gives another upvote to the previous submission. Beyond that time window it treats it as a new submission. I think that window should be expanded a bit but there’s no perfect solution here since occasionally we do want to just discuss the same thing again.
