A while ago I asked for a loan deal and was given negative trust for some reason.
Asking a question like this means that you didn't understand at all why you got the red trust, because @condoras immediately answered you with a link explaining collateral.
Some reason is not something imaginary, but something that exists to prevent people from cheating on other people, and looking for 1 BTC just like that online definitely raises the red flag.
No one was hurt, scammed and no thing was exchanged. Is there anyway to take negative trust off my account for asking a question. Because this is pretty unfair and vengeful of people who don't for example know me as a person.
It is not a matter that no one is scammed, but it is a matter of prevention so that it does not happen at all, and your action provoked a reaction that is completely justified by the standards of the forum. The only way to fix this is to contact the members who left you a negative trust and try to convince them that you didn't mean anything bad and that you regret your actions.
