More trust ratings does not equal more protection, it means LESS as I already explained.
I didn't say anything about "protection", only about due diligence. If people want to be reckless that's their right. And no, you haven't actually explained your theory that more ratings "provide cover for scammers". It would help to have some examples of scammers who are scamming in the current system and would be prevented from scamming in your proposed system.
Just because it is supposed to work that way doesn't mean it does or that it ever will, and after years of this horse shit it is not looking good. This standard will only work if it is implemented top down. That is how standards work.
This implies that someone would need to moderate the trust ratings and either remove non-compliant ones or exclude the users who post non-compliant ratings, i.e. enforce the standard.
At that point might as well get rid of the trust system and ban scammers instead.
