Not sure if this has been suggested or not, but what about a list of "similar articles" below yours (based on a search of past articles based on title/content/etc) so that you can verify yours is unique?

It's an interesting idea, and could be useful. I think that finding a selection that matches your intended submission could be difficult. Would be cool, though.

Technically not difficult, but would add quite a bit of complexity to HN in order to fetch and store at least a fuzzy hash of the article bodies.

From there it's mostly a case for a bayesian classifier (LSI) and some elbow grease.

FWIW, the "similar articles" footer on most blogs is implemented that way.
