What do you purpose as a better trust system? If the trust system is used correctly then it's fine. When people request staff to get involved in the trust system and to moderate it, that's just silly. With quick research about the user who has given bad feedback to anyone. You will see if you can trust that. I don't trust someone because they have a few good trust ratings. I first search up those people who gave them trust. The trust system is there to help. Not to seal the deal. It's a guideline which when used correctly is very effective.
