If you feel DT has left you frivolous or unsubstantiated feedback, make your case. It's as simple as that, and the only way to shape the system to work for everyone. If people agree with what you say, it can be discussed with whoever left the feedback, and if people lose confidence in how they proceed, they just might get removed or excluded from enough lists to be removed from DT.
Hardly I see somebody making a case and winning. More the they try to argument/defend more the forum dedicate itself to find the facts and bring out the more shady facts/past.
Using newbies account simply means that posting from real account may posses lot more damage to OP , if the real account of OP is dig out.
Do you think anybody complain without any issues?
