But who are these people in the default trust? Dt1 people? or both dt1 and dt2?

The members are randomly selected every month. The eligible members consist those who meet certain criteria explained here:

I will periodically (maybe every month) be reconstructing the default trust list to include everyone who matches these criteria:
- If rank was determined solely using earned merit, then you must be of at least Member rank.
- You must have been online sometime within the last 3 days.
- Your trust list must include at least 10 users, not including ~distrust entries.
- You must not be banned or manually blacklisted from selection.
- You must have posted sometime within the last 30 days.
- You must have at least 10 people directly trusting you each with an earned merit of at least 10, not including merit you yourself sent. These "votes" are limited.
- You must have at least 2 people directly trusting you with an earned merit of at least 250, not including merit you yourself sent. These "votes" are limited.

The administrator of the forum publishes the list of members selected to DT1 at the beginning of every month. As you can see in the link, there are 151 members who qualified to be on DT1, of which only 100 are chosen.

DT2 members are then, in turn selected by those who are on DT1. Any member can be selected to DT2, it only takes one DT1 member to include them their custom trust list, unless that DT1 member has been excluded by more DT1 members than those including him. Those on DT2 can select members as well, and they're reviews will appear as trusted feedback as well. If you've left all your defaults set, that's how it appear from your perspective.

On your trust settings page you can change the depth to 1, which will mean you'll only see DT1 and DT2 reviews as trusted. If you set up a custom trust list, only ratings from those in your trust list, and the members they've included will appear as trusted review.
