Other than a MM and a few X whackos, I don't see a lot of this.
I firmly believe the sales are taking place, but I do agree that because Swetha is a such a massive outlier and Daniel Negari (the XZY registry owner) has such a shady past, many feel there is something more to this story, and from past experience, there usually is.
I've been involved in many different business sectors and whenever someone is posting consistently unprecedented results that absolutely annihilate both the base market and everyone else involved in it, then there is usually a second part to the story.
What is consistent is that the majority of the people want to believe, so they do, sometimes aggressively so. But that's just human nature for the unwashed masses who believe that they too can make consistent 5- and 6-figure XYZ sales.
Me, I don't believe it for a second.
