Although everyone has their own understanding of sending feedback, including/excluding anyone on their trust list but I think we all need to be more careful when leaving any feedback to anyone.
You've got a point there. Providing feedback, whether positive or negative, should be done with care and supported by evidence and references. However, trust is a subjective thing. What I find to be trustworthy might not be the same for you, and the opposite could be true as well. It's up to you to decide whose feedback you value and whose you take with a grain of salt, and adjust your trust list accordingly.
Just because one good work that happened out of no where, we should not start leaving feedback no matter that is from a DT or none DT member.
Why not? theymos
[Trust summary] has done this on more than one occasion. How many "good deeds" do you think someone needs to make before they earn positive feedback and trust from someone?
No. Each individual's feedback should be evaluated on its own merit, based on the evidence and context provided, regardless of their status within the forum.
