You are wrong, it should be a concern.
For example, it concerns me a lot because I am an honest and fair person, and I am also very impulsive. It infuriates me when scammers deceive naive fools.
I don’t consider XYZ domains valuable, but one-word domains or good two-word domains always have some value. Not 5-number price, but something—they are worth something... or could have been, if not for Swetha’s fake sales. They have ruined the remaining reputation of XYZ domains.
Their plan is very simple: the XYZ registry marks all one-word domains as premium with high renewal fees, and they do this with every dropped domain. As a result, Swetha ends up being the only one with one-word XYZ domains with standard renewal fees. Then, they "sell" these domains and report the sales.
Yes, I believe that some XYZ domains are sold for $1,000–$20,000 or even more per domain. However, these sales are driven by the hype created by Swetha. And it's also possible that someone else decided to use these transactions as a way to launder money.
I understand that bluffing can be a business tactic, but Swetha takes it a step further by coming to the domainers' forum and reporting fake sales. How many newbies have lost money trying to replicate her "success"? This isn’t just bluffing as a business tactic—this is outright fraud.
