Why would staff be any better? If we were given the ability to moderate feedback then you'd likely just be complaining about us instead. Besides, you only have neutral feedback.
Second that. That's what came to my mind when I read the post. The blame will never be ended even if it moderate by the administration or staff.
By the way, everyone could leave feedback as they want and it's a right as a member of the forum. But only feedback will be visible left by default trust members. And default trust members aren't the same as a regular members. Default trusted members are voted by the community or selected by some other default trusted members. Means their feedback has value somehow. The feedback is either false or right, it will not prevent you from using the forum and you have the right to open a thread if you wrongly get feedback. The community has the right to remove someone from the default trusted list if they think your feedback is wrong. If the community doesn't respond on your reputation thread means your blame isn't valid. That's how feedback is controlled by the community, and it should be.
