Trusted feedback is the feedback left by people in your trust network. It includes scammer feedback.
Anyone can leave untrusted feedback, which means it's easy to game with sockpuppets, so it's not counted in the score.
Anyone can left trusted feedback too by not adding anything in risked bitcoin option, I mean someone with multiple account can get trusted feedback by giving feedback to himself.
then what's the point of it?
What i am trying to say is,
Untrusted (Neutral) feedback should be used for those peoples who tried to scam you but didn't scammed, Not for someone who completed deal.
If it will be simple it would be good and admin should make reference link necessary to avoid fake feedbacks
