I don't know, I have not checked. VC needs to train the people in the quality control team, that's a sure thing! Their automatic calculator is faulty, that I know for sure. I have sold a little over 50 luxury items and all have met quality control. Yet, my rating is not 100% and nobody can explain why. It is ridiculous. Maybe the same is true for you? I look more at the ranking level than the %, my ranking is 321 which is pretty good IMO.
What is the criteria for the ranking? I have not found an explanation on the site about how it is generated. Is it in regards to how many items you sell, how many followers you have or how many people you follow? It seems to be quite arbitrary. Is there a points system based on the name brands you sell? I don't know how to use that number as a refection of the sellers items being authentic or conform or not.
