Still I think that you could consider to change it to at least a neutral trust.
Everyone has got an other view on how trust should be used.
Trust: "Risked BTC amount is money that the person could have stolen or did steal. For example, if you do a currency trade where the other person sends first, your feedback for them would have 0 risked BTC and their feedback for you would have risked BTC equal to the BTC value of the trade."
Did they steal anything???
