The law doesn’t care about the value of a contract, it’s enforceable or it’s not, and I don’t think you have the slightest clue how damaging it would be if I were to sue (again I never I would) and it to come out in discovery that the marketplace reversed the transaction I was the buyer and refused to reverse the transaction I was the seller because the seller the supported pays them more than I do and as a result reversed their transaction not mine. Or even a more generous interpretation of your comment that there is a non advertised fee you can pay to reverse transactions after the fact and the same is not disclosed to users and buyers of those particular domains.
I’m just telling a story of what happened, you seem to be arguing and it’s really bizarre. If you wanted to discuss the law in good faith fine, I’m happy to do that, but you are taking everything personal and lashing out with comments like my “low value domain” and just seem to want to justify what they did from error to paying for a special non advertised service that permits reversing sales...so I’ll step back.
