When I made the statement about duplicates, I was referring to a url/site that is already listed in or sitting in an unreviewed in another category. If the site is listed in a topical and regional category (if relevant) already, there is very little hope that the submission will be approved by an editor (in most categories). Why allow submissions of such to clog up the unreviewed queue. This could easily be handled as Rosalind describes.
As I understand it, when a suggestion arrives for a URL that has already been suggested, it replaces the older suggestion, so there are never any true duplicates.
