It's all good, of course it's good to have a laugh. But I know that I'm not finding QS's smear-campaign against my reputation very funny. I suppose that others who have suffered similar issues would feel the same.
I really think he will remove (or maybe better to neutral) the negative trust, but I do not know what you should do. Perhaps you have to repay $usernam aka TF.
Not an option. I never took any money from TF so there's nothing to repay. He essentially tried to blackmail me and say that I owed him "everything I had ever withdrawn" from his service. If I had been able to have some kind of reasonable conversation with TF back then then we might have been able to figure out just where the misunderstanding was. However, he was not interested in talking, he was interested in having his demands met and I wasn't going to submit to blackmail. History revealed him as a scammer and has revealed me as a regular guy who doesn't make trouble. Now, ask yourself this, why I am I going to pay a blackmailing scammer some arbitrary amount of money in order to have a troll on default trust say that "I'm okay in his book"? That would be an absolute disregard of principle and I'd rather leave the false accusation from Quickseller up there alongside TF's false accusation than pay them money to take them down. Given the way he treats people, I'm pretty confident that we'll be finding Quickseller on the trashbin of history alongside TF in the future. For people like me who aren't doing anything wrong, it's best just to let the theives and criminals and hotheads burn themselves out.
