I don't think anyone was taking away the authenticity of his sales, but then again, I can't speak to the authenticity of his merchandise. They were pointing out that he was cheating the SF system by asking questions and answering them every now and then to keep his thread toward the top of the list to get more views. You may or may not be scammed. If he is selling authentic stuff and you got it for a good price, then there is no scam. But i would be weary of doing business with someone who would knowingly and willfully break the rules of the establishment he is doing business in.
