I think, its better from now on, only hero and legend had the ability to give trust. If other member had a trust problem they can report it to a dedicated thread. This way trust abuse will reduce.
You cannot have a fair system if you are restricting members, but until they are a default trust member these trust given can be neglected.
@OP as far as i am concerned you do not have a negative rating as they are not in DT1 or DT2 and trust ratings are not moderated. If a default trust member come up with a trust rating that you are not acceptable then you can dispute and the forum members will give you a resolution on the situation and if you are not done any wrong then the community will stick to you.
