This is really funny. Feedback by nature should not have ACLs. This system promotes cheating since people can privately agree to add each other (or pay someone with a higher level) and gain powers. Also the system is way too convoluted and unfair towards Newbies and Coppers. Anyone with powers can stick a 'scammer' sticker on a newbie and the world would think so as well, they have no opportunity to clarify it, they would leave a review thinking that the world can read it, but they would be ignorant of the truth. The system should atleast make it clear that although they are leaving a counter review, it won't be visible to anyone except them.
The system is designed fairly so that you will only get power here by proving first how reputable you are through good deeds and multiple successful transactions with other user with proof.
Vod attached reference on his tag to you which is valid. His DT power can be easily removed once he show an abused by excluding him to the trust list of the other DT. Forum DT works perfectly on anonymous environment like Bitcointalk. It’s not unfair with newbie, If you don’t want to get tagged then don’t do shady things like what you did because it’s an obvious fake feedback for your service.
