This is exactly why I don't buy anything brand-specific on Amazon, nor anything that I would ingest or put on my skin. Amazon has offered sellers tools to take down fraudulent listings by others, but I feel it's too little too late. This bribery scandal is just one more reason why I would only buy things like books from Amazon. For other items, I buy from online retailers who have control over their supply chains.
I use amazon a lot when shopping for little gadgets and gizmos, stuff I can't find locally. I do a lot of research, and generally check other sources to see the real ratings and quality of the products. I must agree, Amazon definitely has an image problem going into this decade.
