Some may argue you were trying to abuse the system by attempting to essentially buy trust. You'll have to work it out with him, but I don't think he did anything wrong here, especially when you were quite open in what you were attempting to do.
i simply stated that i wanted to establish myself as trustworthy, and request to receive positive trust after completion of a trade. how does that warrant a negative trust. this is bullcrap
Can you not see how trying to buy trust to make yourself appear 'trustworthy' makes you the exact opposite?
