If this is really such big problem, wouldn't it be easy enough to simply check the link that someone is attempting to submit against all previously submitted links?
This wouldn't necessarily stop all repeat stories, but it seems much more feasible than hoping everyone does a search, and would at least stop people from uploading identical links.
You might also consider a time bar of some sort? Say, if the same link was submitted more than xxx days ago, it can be resubmitted, since there is a good chance there is something new to add to its discussion.
