First off that is a stupid price for a stock.

But I can understand the seller, perhaps. He may actually think it is a Win stock. He gets an email from someone saying that it isn't. If I was him I'd immediately go defensive - not because I am trying to misrepresent - but because who knows who the person is on the other end of the email. It could be a buyer or the friend of a buyer trying to get the Win stock for a cheap price by saying it is fake.
