In general, I'm in favor of giving DT a possibility to remove certain feedbacks, for example if at least a net amount of 5 DT1 members would oppose a certain controversial trust feedback, these feedbacks would vanish in untrusted feedback, even if it's a feedback from a DT1 member (like our case here) if enough DT1 members agree on removing it vs. don't agree to remove it.
This is interesting. I guess you mean being able to vote, for example like with flags, but with trust feedbacks. I think the idea is worth to open a thread in Meta
, it didn't happen.
