Is there anything that can be done to resolve the negative trust or is this the final judgement on this account?
As far as I know, you can PM them and provide proof if their accusations are false. You can also create a thread equipped with evidence that you don't deserve to be tagged negatively. However, if their accusations are true, it is better to forget it because that is the final decision. Besides, you are dealing with those people (who tagged you) and 1000% they will not change it
But you don't need to worry because with a negative tag you can still discuss... So it's no problem, right?
