Thanks for clearing that up. People on the default trust list or however way you get the power to have a -6/-1 feedback rating need to use it responsibly and from what I've seen it's being used for the wrong reasons so the people who have it either need to start using it right or it needs to be deleted all together. Using your forum power because you're mad at somebody doesn't show the maturity level you need to hold that kind of position on the forum no matter how much you've helped the site out because it's ultimately hurting the site.
There is no sensible way to moderate people's trust. What you are demanding is impossible to be delivered without there being other tremendous pitfalls being created by dictating to other people how to use their trust. You might think it is for the wrong reasons, clearly he thinks it was for the right reasons. Uninterested 3rd parties have no stake in making sure justice is done, only in making the drama go away as quickly as possible. Because of this strategy, all a troll has to do is kick ans scream and the mods and staff will come running in an endless self fueling cycle of troll-baiting of trusted members followed by claims of abuse. Trusted members operate IN THE OPEN. Trolls use endless disposable accounts. There is a cost to operating out in the open so that people know you can be trusted, and people who are reputable should be supported, because they are what makes this community work, not the trust system.
Being in the default trust is not an elected position. No one on it signed up to be a servant of the community even when it costs them personally. We got on that list for demonstrating we follow through on our agreements and operate in an open an honest manner. A long history of operating in a reputable way does not some how create an obligation on the part of the trusted party to serve you as if they had some kind of capacity of a public officer. Basically what you are saying is you were joking with this user on a professional thread of his, he did not find it amusing and left you a negative trust. Now that you are faced with the consequences of your actions you demand that he uphold the good name of this forum at his expense, but you yourself hold no liability in this circumstance.
I am sorry but I am having a hard time having sympathy for you. Maybe if instead of making this big thread about it you simply apologized to him and asked for him to remove it he would respond, but of course not. What fun would that be? You would rather escalate this like all trolls do.
