I wonder how did the submitter this time come up with a tag '/?_nospa=true' at the end of the original url. ( http://j2kun.svbtle.com/you-never-did-math-in-high-school/?_...). Is it a way to resubmit an old item to HN again?

Hadn't noticed that, but yes. Putting in content like that can get around the duplicate filters.
