I agree with theymos points and I think a lot of people on the DefaultTrust list are looking at their role the wrong way. A few think they are doing good by squelching any sort of scam attempts by that user because they made some mistakes but really we should be looking at how you are impacting everyone including the member in question. People make mistakes and I can guarantee if we went through some of the DefaultTrust members history they would have made a mistake which could well have resulted in them on the negative list. DefaultTrust need to take a look at themselves and decide whether the greater good is always the best choice.
Speaking more generally, people who immediately start a thread and dish out abuse in retaliation for their red trust almost always end up with more. Take a break, take some time to cool off, and then come back and present a logical case. And as theymos has said, DT members should also be more willing to remove tags left for less serious issues.
Cryptohunter should probably be dealt with by the moderators as he constantly derails every single thread that he posts in. Including this one its now turned into a thread about him and there has been several low quality posts not just from him addressing it. Instead of constantly arguing over negative feedback consequences need to happen with constantly derailing threads. I'm personally sick of it because the majority of threads in reputation is about this incident and it even leaks into meta.
