Giving someone negative trust for disagreeing with you sets a dangerous precedent and degrades the value of the trust system overall (especially if you are part of DefaultTrust)
The situation with WC has been unique to say the least, threads cluttered with alt accounts and shills. To say that Nubbins is tarnishing the reputation of honest users is a bit much. There has been some deceit from WC and Nubbins has tried to caution new/old customers to look closer at what they are actually purchasing. He has certainly been aggressive in his methods.
I think Nubbins should be educated on how his trust ratings are affecting users not confirmed to be scammers before being removed
