If you don't really understand how trust feedback are done

This just a basis trust feedback be it positive or negative is give by only a DT and not just by any user

And there are always a reason for it although not stated on the profile just like when ever you get banned the reasons are not stated till you appeal.

And DT are reputable members and are not bias in the dishing of trust feedback so you can count on them Even without leaving a reference so things are better concealed till when the matter arises to keep a healthy balance of the forum
