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. However, this doesn't prevent multiple deeplink suggestions.

One solution for this would be to disallow all deeplink submissions via the add-url form, but allow editors to add deeplinks. Then compile a list of exceptions to this rule for websites such as Blogger, Geocities, and other providers of free hosting. And for those exceptions, allow only one deeplink per account (so you would get only username.example.com, rather than username.example.com/something.htm, username.example.com/other.htm, etc).
