A simple crawler would have been able to detect it’s from 2006. Perhaps a reminder should be added if the year is not recent

Even simpler, just check if the url or title has been submitted before. That would also take care of all the duplicate entries that pop up once per day for a week after a viral story is emerging.

In this instance, the url is slightly different from previous submissions so some more clever fuzzy matching or using only the title would be needed.

Yes, I have always wondered why the simple duplicate checker within the same couple of days does not exist. Or does it exist and the duplicates are actually sligt variations of the URL.
