I do not know much about the trust system but the reason why am not interested in adding any member to my trust list is because i haven't built enough reputation yet, when i do i will add users that i trust.
That is not how it is supposed to work, as I said you should add users if you trust their judgements are accurate and that's what theymos suggested too. quoting the post here
Also, it's best to make your own custom list, and you must do this if you want to be on DT1.
Also you can learn more about that in detail with LoyceV's Beginners guide to correct use of the Trust system
What actually led me to create this thread was because a saw a staff being given a negative feedback by a member who is no longer active in the forum for about 5 years. I saw that Lauda gave EFS a negative feedback and looking at the profile of Lauda he has many negative feedbacks up to 5 which should have even been enough to remove him as a DT member.
You need to dig a lot deeper to know the legacy of Lauda and (her) contribution to Bitcointalk in many ways. At one point, with the most number of posts, and even now, with probably the most number of feedbacks left, the list goes on. So, don't come to any conclusions without knowing the full story.
DT always comes with a lot of drama and not everyone has to agree with their ratings which is why the solution offered by the system is very simple all you need to do is just use ~ and that's it.
