I guess this is more possible and easier if there is a database table of all current DTs. If not it will be hard, as PowerGlove will program/make all the conditions set by theymos for him to get those list. But yeah, it's possible thks way.
LoyceV has a nifty website that visualizes it:
https://loyce.club/trust/ranking/. Usernames with DT1 flags are included in the Default Trust.
Ideally, DT should only serve as a guide and that it should be removed once the user has formed their large enough Web Of Trust.
