Hi adit999,
Like I had mentioned earlier, eBay does not take any judgement on the authenticity of the products. If the Rights Owner thinks that the item in fake (complete manual judgement of Rights owner), then we take the item down.
Also, while we try our best to avoid buyers buying such items, in case buyer buys it before we remove it, we protect the buyer under the buyer protection program.
Regards,
Sapana
