Obviously you must be doing a great job, and they just hope you might give some clues out. I have had people copy me all my life, my clothes, my hairstyle, the colour of the paint on my house, my garden. Often people directly asked me, knocking on the door, what plant is that? What colour is that paint? It can get annoying. What they all fail to realize is that the paint went with the colour of my bricks, the plants suited the style of my garden, the hairstyle suited me, as did the clothes. All of the so called copying never looked the same as what they were trying to copy. My point is, that even if you told them all your secrets, they would not have the same success as you, as there is more to just making a good listing, it is the way you handle your sales and treat your customers that ensure your success. Take it as a compliment and tell them to figure things out for themselves.
