Are you willing to cover all losses from scammers who's negative trusts were removed this way, which deleted all references to being a scammer on their profile, and allowed them to scam someone else?
I have only been here 1½ year. As I see it the trust feedback it not used to prevent scam that much. But mostly to tell new people how to act. And therefor when they learn along the way they should have a chance to remove 1-2 feedback yearly as I see it.
Edit:
You are one if the few I have seen that actually try to fight spam with the system. But in generel I mean.
