Great, I can finally get double the amount of "Lauda gang" complaint threads. 
Do not worry, whatever the system in place,people will always complain.

I will simply say if we can create the system that DT feedback will be applicable only if it supported by 2 other DTs.
That will make the system even more inefficient to the point where I bet DT members would stop tagging anyone. What am I supposed to do when I find an account seller and want to tag him--drop a PM to another DT member to request that he cosign my negative trust? Wait for a response and if the answer is no, then move on to another DT member? What if I get scammed myself? Am I then not allowed to leave a neg unless I have approval from someone else on DT?You are still free to leave -ve and I like LoyceV suggestion that not every account (at least high ranked account) should be destroyed by single -ve or some personal issues with DT member.
It is also ok to leave soft warning as suchmoon suggested but I think it will not solve the purpose because a -ve rating will still be negative, does not matter how it displayed but if first negative rating changed to " ? ? ? " then it might serve as warning and everybody should be cautioned.
My personal belief is that when you are trading with someone then you need to check every feedback (trusted + untrusted) to make up your mind but unfortunately people are just guided by trusted feedback only. DT are human and can err in some case but why everybody is putting a blind eye to that feedback and making a de facto standard.This is the reason I suggested 3 people cannot be wrong at same time.
Anyways in my belief, when you trade , you are supposed to use escrow and protect yourself and the responsibility to protect you from scam does not lie at DT at all.
That's a problem with signature campaigns, not with the trust system.
the problem is indeed with the trust system.I believe the root cause of the problem is account value. Most of users in bitcointalk set some value of account in their mind based on the ranking of the account. That's why you see thread like if you are legendary/Hero or green trusted account I will go first (completely ignoring escrow) or will not deal with -ve trust account or below Member ranking. Moment you get -ve trust from DT the value of account change to zero and you lose many of the trade/earning opportunities exist in this forum.
