This site currently is one of the busiest bitcoin websites, yet it hamstrings bitcoin by catering to scammers and trolls.

1) It should be a matter of policy that anyone making false/unprovable accusations against another member be banned for trolling. That's all it is and it should never be encouraged. This assumption that everyone is an idiot, and one member decides he is some kind of cape-wearing hero that must save the world only creates a toxic environment that hinders commerce.

2) The ridiculous "trust" system allows anyone to troll anyone, often with fake + and - comments. Examples being that much of the positive trust is left by one user with multiple accounts, while the same users troll competitors with negative feedback.

3) Nobody should be able to "rate" another user without having done business with them directly, and it would not be too difficult to create a system where two or more users agree to a transaction and allow themselves to rate each other. This record could then be publicly displayed.
