In my experience with ebay, they said my zebra yeezys were fake when I got them straight from adidas. The only thing I didnt have with me is the original box. When I asked ebay what did they specifically see that made them question the authenticity of it, they declined to answer. So I dont believe ebay is a top authenticator either
They wouldnt authenticate my yeezys when i bought them straight from adidas. They claimed that someone mightve bought a pair from adidas, switched them out with fakes, returned them to adidas and then I receievd the fakes. Nobody was returning yeezys in 2018/19
