> This could definitely be abused if someone orchestrated a large purchase & return campaign

I don't think so. For a very popular book, the resources needed for this would be enormous, as there would be thousands of other, legitimate buyers.

For less popular books, noone would bother anyways.

It would depend on how the algorithm worked & the policies are setup. In many cases those with lower volume products are held to more stringent standards than those with higher volume products just due to base costs. If a certain product is spiking in customer complaints or returns relative to similar volume products, then the distributor will probably cut their losses. Also what's considered low volume to Amazon is probably different than what a person making a living selling books or apps would consider low volume.
