I buy a domain, and let's say it has 10 percent chance of being sold for 1K in the first year. So it is worth $100 to me. A fake buyer shows up and I "sell" this domain at Sedo or AN for 1K, but it remains unpaid, and let's say 1 month of waiting time is wasted and in that period I may have missed some real offers. So it is like, anyone can steal my $10 (corresponding to 1 month of $100/year), and marketplaces help such fake buyers with their fake purchases. This needs to be stopped !!! It is very easy. 1. A user should pay $10 to the marketplace just before placing a bid. 2. It will be refundable if the user closes his account, or if there is no active negotiation or transaction. 3. If a deal is made, but cancelled, and the buyer is the guilty party, then that $10 should be taken form user's account and should be paid to the seller. This would be a legitimate earning for the seller, because he is wasting his time, and may be missing real offers, because of such fake transactions. And "buyer"'s account would be closed after second violation. If the buyer wants to cheat again, he will know that he will have to pay another $10. More than one cheating, should mean permanent ban, if detected. I believe/suspect, marketplaces are not willing to do this, because sometimes they act as broker, instead of a marketplace. This explains tons of lowballs and unpaid sales. If marketplaces are honest, and they are just getting the percentages, and not playing some other dirty games (more dirty than shillibidding), then making such a change in their system should be to their advantage as well. Because the more and better sales we make, the more money they make, because their earnings is just a percentage of ours. By not making such a change, I suspect, marketplaces are admitting being fraudsters.
