When the MBA team reviews new submissions, they could rate the uniqueness of the designs e.g. using a scale like 1 (many similar designs exist already), 2 (some similar designs exist), 3 (very unique). The higher the rating, the higher the initial ranking of a new submission. This would have the following advantages:
- MBA would end up with a more interesting store.
- Sellers would get rewarded for originality.
- Buyers wouldn't get inundated with lots of almost identical "papa bear" tees.
- Copycats would get discouraged.
