For years I've been unhappy with how DefaultTrust ended up as a centralized and largely-untouchable authority
How it worked: Theymos adds some selected members as DT1 and the DT1 members add users in their network who they trust, they become DT2.
For the record DT level can be extended up to DT4 (please correct me if I am wrong) but anything over DT2 is always ignored because it includes almost everyone which does not create any value for the network.
The current DT network: In January 2019 Theymos decided to change the old algorithm. Without giving all responsibility to one member (theymos) he decided to have a voting system for DT1 members and the voting system allow to select 100 members in the DT1 network to make the entire network decentralized.
So if someone on DT1 is doing something stupid, you can ask other DT1 members to distrust them.
TL;DR;The current system created an open area for anyone to be in the DT network. We add, remove a user in our trust setting depending on their judgement of feedback leaving to others based on how is less their retaliatory mindset. Obviously none of us are perfect, none of us are above our personal likes and dislikes. But when a user's feedback leaving is (1) clearly out of retaliatory, (2) clearly to hostage others to silent against him, (3) clearly based on inappropriate arguments, (4) clearly using it to scam others would you still add him in your trust network or you will tilde (~) him?
Warning: Be BOLD and brave, who do not care for a negative feedback and a tilde (~) before leaving an opinion. Here are your examples:
100% retaliatory negative feedback:
