If OP can prove his account is not a bought one, he has the right to require the removal of the part that says his account probably is bought, even if the negative trust remains.
And I understand why hilariousandco left the feedback in the first place, but since the escrow offer is not open anymore I think the trust should be changed to neutral after some time, if OP don't show any potential scammy behavior(just personal opinion).
The fact that your account is really irrelevant to the nature of his trust. The fact of the matter is that you have zero trade history where you were trusted with the month of your trading partner and have zero trading history where any money was actually exchanged. Yet you are still offering a service that would require others to trust you with their money.
Why would it be a good idea for someone to trust someone with their money when you have no prior trading history? Don't you think it would be better if someone were to "roll the dice" with their trading partner and hope they are acting honestly? Don't you think it would be reckless for someone to trust a person with no history of acting honestly with other people's money with their own money?
The question of if your account was sold or not is only distracting from the question of if you should be trusted with other people's money, and if people should trade with caution when considering to deal with you. I would personally think that you should not be trusted with other people's money and that people should proceed with caution when considering to deal with you. The negative rating hat hilariousandco gave you (and the one that I am about to give you) is a warning to others who are considering to trade and/or trust you.
I am somewhat surprised to see a thread about a rating that hilariousandco gave as he is normally very conservative in giving out negative trust. This does not mean that I think he should remove the rating, it is just that it is nice to see a trust related thread in meta that is not about quickseller.
OP is not offering escrow anymore. I understand why hilarious left negative trust for OP, but in my opinion yours is unjustified because OP is not offering escrow at the moment(just my opinion please don't act like I'm insulting you or something)
