The major problem with the trust system is the selection process for those who are on DT has nothing to do with who actually uses the trust system in a meaningful way (eg, they don't participate in the marketplace in a meaningful way). As a result, the DT system is not one of self governance, but is rather something closer to a dictatorship, in that those who make the rules are entirely unrelated to those who are bound by the rules, and those who are bound by the rules have zero input in the rules.

Those who are in DT are also not selected by those who have ever been active in the marketplace.

IMO, the best way to structure the DT system is to have several people who own, or have owned large bitcoin related businesses who have people on their trust list they are willing to trust their businesses' reputation on in regards to giving fair ratings, and otherwise acting fairly within the trust system. When there is a rating dispute, if someone is not acting in good faith, or otherwise is acting fairly, their sponsor(s) should be called out publicly.

The best and most appropriate people to run the trust system is those who are wanting to protect their (potential) customers.

Looking at the first 3 pages of the digital goods section, it looks like nearly all of the threads are scam attempts, or attempts to do something illegal. The services sub is made up almost entirely of signature campaigns, the currency exchange sub has few active threads of people conducting legitimate business, and very few loans are ever made in the lending sub.
