Amazon taking action against the vendor, and consumers blaming the wrong vendor.

When you order from Amazon Marketplace you can clearly see who you are ordering from, even if Amazon shipping the item. Consumers getting a bad product will then no only review the item but the seller with negative feedback even though the seller they bought it from may have done nothing wrong

Of course the real problem is the counterfeiters have no problem starting a new vendor every few weeks or even days, so the damage may already be done by the time the reports come back.
