I would also say that it is not safe to assume that the trust is for the sale of the account because of the time difference. According to zazarb the deal was on Dec 17, however according to the screenshot in the thread in meta(that will likely get moved to reputation), the trust was left ~2 weeks later on the 29th
Alright, let me rephrase it. I personally got the feeling that this trust was leaved over the sale of the account (checked both accounts posts in the 2 weeks from the sale to the feedback).
But since I can't bring up any more than my gut feeling for this I came to the conclusion posted earlier:
However, a neutral should sufficient.
I do not know reason for this feedback, but you free to ask bitkilo, maybe he
provide sufficient refference to you,
my suggestion- let speak, and the other side before accusing.
