That's good for Amazon, but from a consumer's (and responsible vendor's) perspective, until a bad actor vendor gets caught by this system and kicked off Amazon along with all the reviews of their counterfeit/bad inventory, consumers have no way to protect themselves. A consumer on Amazon cannot even protect themselves by ONLY ordering from Amazon's own seller listings. I've done that myself and ended up with used/repackaged stuff sold as new.

It creates a natural "market for lemons" experiment on Amazon. I can't imagine that is healthy for Amazon in the long run.

With their transaction volume, Amazon should be able to detect and properly address these reviews. You're not going to change consumer behavior here, it's on Amazon to adapt.
