My take on this has not been that the sales are faked, but that Swetha has a connection with the XYZ registry owner and is essentially handling and reporting direct registry sales (and sales from registry leads) in order to build momentum and help draw in more private investors.
It would fit, as she has all these miraculous sales, while everyone else is floundering with industry-low STR rates and wondering how she does it. Afternic recently issued some data and it showed XYZ at the very bottom (by a long shot) of the STR chart.
It just doesn't make sense that Swetha is a 100% above-board private seller with no link to XYZ, and just happens to be the luckiest salesperson on Earth. I don't buy that.
