Today I accidently uploaded a dupe of http://whatthemovie.com/shot/26315 However, when uploading the still, at the point where you can double-check whether the still has already been placed, the still was not visible. Maybe this should be changed to avoid dupes being placed.
Of course it's not visible. It's still in the FF. How do you expect the upload system to make the difference between a dupe and a legitimate different shot from the same movie ? ;)
