Rules work only as far as you can enforce them. So who's gonna enforce the rules? Who's going to have the power to remove ratings or remove people from DT?
Honestly default trust imo is just a very outdated judge of a completely different forum. More than half the people on it are dead accounts, or people who rised to the DT status by the amount of time they spent on the forums.
But if there's one thing that doesn't make sense it's completely biased judgements that are in no way related to an exchange of goods.
Like, sure, I get that someone trusts another person and tags him accordingly, or that someone else doesn't trust another. But isn't trust supposed to show the financial honesty of a person? If someone can be charismatic enough to convince 5 other members to trust him that's great, but if another person with questionable opinions had over thousands of dollars in trades is less trusted than this charismatic person... It really skews the meaning of "Trust" on the forums.
That's why you need to read the ratings and/or use custom trust lists.
i also might have screwed up when i used the word "regulate" , excuse my mandarin 
. i am not saying the trust system should be controlled by the mods as this will most likely make it worse, i am saying we need a set of rules, so when someone is not satisfied with the tag he gets, he can then complain or appeal based on an existing rule. it will be much easier to judge the case if we have such rules.

who is enforcing all the other rules on the forum now ? who does the ban/unban any other types of things? rules will be enforced by the same people/person.
if someone can get you banned then you shouldn't worry if they will abuse this one set of rules, for all we know theymos can ban the whole forum and he is not obligated to even explain why. so there has to be some sort of authority to handle the rules.
once those rules are set, DT members will have to follow the rules, and once they don't which will be rare then even theyoms can attend to that. it will not be an every minute job as we only have a handful of feedbacks that could be considered as a break of rules.
So this would put the control in moderators' hands. I don't think that's an improvement at all.
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.
