Which new DT2 members?
Can you point us to DT2 members who are leaving useless feedbacks, point us to these useless feedbacks and explain why they are useless?
I thought it was a bit confusing in several of your replies but it seems that you don't know you were included into DT2. Given that you most likely don't care and manage your own custom trust settings, it may have been that you thought the attention was just a coincidental period of activity.
Have you contradicted yourself?
This is not a contradiction. Exclusion =/= Negative trust. It simply means you do not trust their feedback. However, you can still trust the person.
