I hear this stuff about ebay all the time. I'm surprised that Amazon is having a hard time with this too. The real problem is that there's really no way to insure that a Marketplace seller is selling legit product. The best you can do is report them so that Amazon is aware.
Amazon selling fake stuff, is not anything new to me. I have always known both eBay and Amazon for selling stuff that was not authentic. The only reason they do so is because they actually get the items very cheap. Then they sell it for even cheaper. You just have to be able to tell which items are fake and which items are not.
I am sure there probably are bad traders selling fake stuff. Amazon is huge, I doubt they can monitor and control what every trader is selling, that would require a lot of staff. I have seen fake products sold on eBay as well. You should be able to report anyone selling fake goods, they will be removed.
