You do not have a negative trust, so why do you want to get rid of negative trust? You want to get rid of what you do not have. Or you meant, how to avoid it?
I get the impression OP wants to have a discussion about it, maybe to clarify what's being written on telegram or other sites. And if any of those people were actually members here for any length of time, they ought to know that it's not a complicated situation. A frustrating one, maybe, but very uncomplicated. The person who left you the feedback is the only one who can remove it.
Why am I the only one reading another meaning into the OP? I believe the OP is a victim, but he's trying to play smart because he knew he wouldn't get a good response if he posted from his original account, and if not, I don't see why OP would bother looking for something he's not a victim of. I could be wrong, but these are just my instincts.
Maybe that'll change, but somehow I doubt it. It's been that way for years and it doesn't seem as though Theymos intends on changing things.
theymos prefer that everything be decentralized. I doubt he would as well. Although some users are victims of DT abuse from old members who are no longer on the forum, there is no hope for it to go away, which is another disadvantage of decentralization. Everything that has an advantage also has a disadvantage.
