Welcome back.
Though I must imagine you have been keeping up with the forum just not logging in or posting. I'm just going to disagree with you on your left feedback. While your opinions are your to have and use to shape how you interact with others. The trust system as a tool, like all others, a right and wrong way to be put to use. I'm sure I'm beginning to sound like a broken record, but it has to be said. This is at best a neutral, there is no grounds for a negative feedback in this case. Your reference should in fact be pointing to a case of them scamming or trying to scam an individual. The course of action that you should be taking is ~ them from your trust list as you don't trust their judgement. Beyond that you can say anything you like about their character and poor judgement in defending those that you find indefensible in a neutral comment on their feedback wall.
I'm sure the discussion here will go over my head at points, I can admit it especially when some of it become tl;dr in regards to having to reason why we are doing something. There is a clear intent behind this new system and I don't understand why intelligent individuals are blatantly choosing to ignore the intent behind it. Actions such as this are honestly only emboldening the individuals who feel on the outs, or that having opinions are why they are targeted. They then use these instances as a lightning rod to others, and they aren't wrong when they get handed these gifts that "prove" their opinions on the system to be right.
I feel you have likely read this, if not I recommend it.
