First: it's nothing personal. I've seen good posts from you, and although there's nothing wrong with being inexperienced when it comes to trust, I don't think you should have your first trial run when you're on DT.

It's not about sending you a PM, which indeed I could have done. You should be able to stand strong when you leave feedback. If you're wrong occasionally, it is of course good to change it when needed, but the majority of your feedback should hold strong. That also means you shouldn't just delete them the moment someone disagrees, you should be able to back it up. And if you can't, that means you shouldn't have left the feedback in the first place.

Deleting the ~dozen positive feedbacks you've left shows you're willing to learn and improve, but it also shows you couldn't make the right decision on your own.

Just my opinion of course
