I wouldn't say I understand the trust system very well, if I would then perhaps I could save my account from the neg by hilariousandco. Anyway it's irrelevant here.

Being a DT is a great responsibility. You are one of those trusted member who are representing the entire forum reputation. It's good to see that you think twice before leaving a feedback and I hope all the DTs do the same, even after they leave a feedback (heads up to marlboroza). There could be situations where you could be wrong for your judgement and admitting it - is not gonna make you less respectful.

The feedback from elsie34 is an untrusted feedback so it does not matter. Seems like the person wanted to give you a positive one but end up selecting the wrong option. I used to leave a neutral trust if I felt that I was given red for a wrong reason (now a days I don't even care ever since I got the red and another neutral from Lutpin. The Lutpin one did not affect me much mentally but the hilari one destroyed me mentally) to explain why I was misjudged. I think leaving neutral is ok when you see you need to defend a red. Leaving red to defend an unnecessary red is kind of abusing the trust system especially when you are a DT coz your trust counts.

Well-done on the topic.

Correct, for a non DT it's ok to do whatever they want (use/abuse of anything), nobody counts but once someone become a DT then they are basically a role model/an example for the forum.
