Ninja uses the actual url of the sweeps to detect duplicates and not the "description" of a sweeps. Many sweeps are promoted on different websites but the referring URL for entry is what's important. If ninja detects the same url in it's database, it gets flagged.
I don't know if Johnathan has fixed a small issue with this yet and that is if you see a duplicate in "your sweeps" tab, make sure it is clicked NOT to enter (a red X) or ninja will enter it again, even as a duplicate.
Hope this helps!
