I am not sure where any of that is coming from. I have a couple of articles on the website about drop-shipping. I know what it is. I said before in several other posts that I only take that as bad with other things: like never selling Lego before, low feedback, non recent feedback, etc.
I don't understand your point at all either. I mean, let's say we are wrong about one person. That's sad? How exactly? So we make one person re-list. On the other hand we can do nothing and all suffer from the price deflation.
I know what drop-shipping is and I know it's not illegal. But 99% of the time, if you are doing it on Ebay, without any other Lego sets in the past, with low feedback, with stupid low prices - you are scamming.
