> It'd be quite unrealistic to have Amazon own the tools and perform QA testing on all the millions of items on their site. You see a similar problem with knock off headphones, even plugging them in and listening to a song wouldn't be enough to find most fakes.

If amazon doesnt have capacity to verify products they are selling, they shouldnt be selling them. They are knowingly contributing to fraud and we write it off as "they're too big to regulate themselves"
