People like me have received much worse in spam trust, quit complaining and just deal with it.
Resolving it or ignoring it are your two options, the trust system isn't moderated as Diamondcardz said. Moderators can't do anything to trust, only admins, and admins won't make any changes to it, as that could lead to abuse quickly.
I think the only time feedback has ever been removed, was when someone was creating bots that would leave everyone negative feedback. They were banned, and that feedback was removed.
So if if you get fraudolent bad feedback there is no way to get rid of it.
This is not good, however i guess that if you could prove your "innocence" in some way, there will be a
little possibility to get rid of bad feed.
(very very little)
Well, as others have said before, the person who left the feedback in this case was added to the trust list of someone on the default trust list, hence the problem; that is, everyone else sees you with the red trust message. But this also means that if it was fraudulent feedback and you can prove it, you have a good chance of convincing that person to remove the other from his trust list, as was suggested, which should solve the problem.
And if I understand how this works correctly, other ways to solve this could be either someone else on the default trust list (perhaps on a higher trust level of the list) giving negative feedback to the person that gave you the feedback, or giving you positive feedback directly.
