I think there needs to be a better trust system implemented. It's worthless at the moment.
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.
Maybe you can only leave trust after both parties have agreed to do a deal. It's silly being able to leave trust for anyone anytime. Can you go on ebay and leave everybody negative feedback without even trading with them?
The system is also flawed because a newb can scam a load of other newbs and the trust wont even show up and he can continue scamming. A honest person can have loads of positive trades and none of them will even show up, but one "trusted" member leaves him negative for no reason and boom, he now looks like a scammer.
