That's how it's been since before you found Jesus and switched from posting bullshit ratings to preaching how proper ratings should be posted. The trust system and DefaultTrust don't prevent or discourage this in any way, and provide the tools (ratings with references) for due diligence.
What you're doing now seems to be aimed at reducing the amount of trust ratings available and only posting them after a scam has actually occurred. That doesn't sound like an improvement to me, it actually sounds like an impediment for due diligence. But you can set it up that way for yourself by building your custom trust list and I encourage anyone who agrees with that approach to do the same. That's how it's supposed to work. Not by implementing top-down rules.
Here is Captain Toadie right on cue to derail more. More trust ratings does not equal more protection, it means LESS as I already explained. If they are for petty reasons all you are doing is conditioning people to ignore them, justified or not. If this objective standard is set then the only ratings left will ACTUALLY MEAN something, and will have proof that can be referenced, you know like one looks for when they are doing due diligence?
Just because it is supposed to work that way doesn't mean it does or that it ever will, and after years of this horse shit it is not looking good. This standard will only work if it is implemented top down. That is how standards work. Unless Theymos comes out and says this is how it should be the confusion, conflict, and scamming will continue to grow.
We need an objective standard of evidence of theft, violation of contractual agreement, or violation of applicable laws for negative ratings.
