Trust is all subjective anyway so it doesn't matter. There is a basic divide in this discussion, those that believe an account sold gets a fresh slate, and those that don't. If all of the people who don't believe they get a fresh slate leave negative feedback,
only those that believe that will care about their feedback.
I will not remove the negative trust, the new owner knew what he bought. As a lot of you said : it can be impossible to determine if the new owner is not associated with the old, in this case we cannot remove the negative trusts.
redsn0w, if I may use your comment to elaborate. Lets say that redsn0w believes what they do, they bought what they bought, no clean slate for them. I on the other hand, believe that after the account was sold, the new owner no longer deserves the negative feedback. If I was to buy a pizza from nyktalgia, I'd look at their feedback to determine the best course of action. I see redsn0w's feedback, but I disagree. We don't need to hold a petition to set trust rules or get redsn0w to change their feedback, I will just personally ignore redsn0w's note, because I don't agree with them on the matter. And we proceed with the deal.
We change the senario, and I'm hilariousandco (no I'm not really, because someone will misquote this if I dont mention that we are not the same person (or are we?)) I agree with redsn0w that the negative trust is deserved. I value their opinion, and before I buy that pizza from them, I take what I consider appropriate measures. My point being, feedback is relative, as long as people explain why they are leaving the feedback they are, others can judge it's validity based on their own concerns. Thats the reason the feedback system doesn't need rules, because each person will use it differently based on the situation and what they personally believe. Numbers and red letters don't mean anything, what matters is the content of the feedback itself. The source it comes from, the reason, and the backing.
