Just read about this in a private forum. Can any of this forums Chinese sellers confirm this?
The word is that Amazon is cracking down on sellers shipping directly from China and freezing their accounts en masse and then going through and approving them back individually.
Specifically, I think this means Chinese sellers in China who list items that they are merchant fulfilling and shipping from China into the USA marketplace.
There was word of too many problems with fakes and counterfeits coming from Chinese FBM sellers.
