The thing is, does Amazon care? They have their "return anything you don't want" customer service to keep people happy (which, admittedly, is a fantastic resource), but they don't sell bootlegs directly (as in, "Sold by Amazon.com"), and the third-party sellers who they act as a distributor for undoubtedly sign contracts that waive Amazon's responsibility in the legal procedures and stuff. "By clicking Confirm, I agree that if I sell bootleg crap, Amazon will not be legally penalized for it." Yes, it would be great if Amazon could/would hire people to do this. But they have nothing to lose besides perhaps a handful of fulfillment sellers or whatever they're called ("Prime Partners" or whatever). Amazon is not content with having the amount of money it does; it wants more, more, more! They're not going to hire people to test for stuff that their legal paperwork says they're not responsible for in the first place. They take their cut of bootleg BS, having waived all involvement in it, and if someone comes after them, it's nothing for them to just give up the $10 cut they took from that $40 Pink Floyd box set just to keep people satisfied.
