I can't see anything about scam here. Why are you claiming on your subject about scam trust system? If you think that they have left you negative feedback's for invalid reasons then go to reputation and open thread, why are you think that your feedback wrong. So others DT will check your post and if they think you are legit then other DT will counter tag. It can solve by discussion. That's not right way remove your feedback.

Your Accusation is invalid
