So this would put the control in moderators' hands. I don't think that's an improvement at all.
the control is already in the moderators hand, if someone can ban accounts then it's not the best argument to say that putting them in control is not an improvement. since we can not have voting , elections or anything of that kind then moderators must have control. in fact someone with the power to ban accounts can ban a DT member right now for no reason so we are not actually giving the mods any sort of extra power. and even if we were to assume so, i personally rather see a moderated trust system than a random trust system, at that point the majority of the feedback will make sense to the majority of people.
Here is what you can do: add moderators to your trust list. You have a moderated trust system, and I get to keep mine too.
Trusting moderators with enforcing rules on spam etc is not the same as trusting them on evaluating nuances of every scam. I would prefer those systems to stay separate.
Even assuming the enforcement can be super fair, it's still not a benefit to have the trust system conform to a rigid set of rules. The variety of opinions is part of what makes it usable. For example when The Pharmacist started tagging account traders I added him to my trust list because I wanted to see which users are account traders. That was before he was in DT. It looks like your suggestion would take away that flexibility if everyone is allowed to tag only for trades. It would also remove the ability to warn about ICO scams etc.
"The variety of opinions" is the root of the problem. you can not have a "The variety of opinions" in a trust system. especially that DT member's tag is the THIN LINE between a usable account and a non-usable account[1].
[1] -almost every signature campaign states that if you have a negative trust you can't join.
-the majority of people will not be willing to trade with someone who has negative trust from a DT member
I mean look at the contradiction of DT feedbacks on the same members, this would have not happen if the rules are there.

I certainly don't subscribe to this hive mind thing so we'll have to disagree on this. Not everything is black and white. I prefer to have an occasional counter-rating or some other dispute than make the whole system rigid.
