Knowing how Seller Performance works, they aren't about to close off a listing that is doing $nn-K revenue per month because of a couple of copyright reports. The economics simply don't make sense for Amazon to poison the inventory of a seller because of a couple of reports, to fix this problem Amazon truly needs to figure out a way to verify the validity of inventory sent in to their warehouses.
That's a question that I don't have an answer to, but I do hope that someone from Amazon is really working on it. Inventory commingling and a myriad of other issues present in the processes of selling on Amazon are the reason that I decided to not pursue FBA further.
