the negative trust in my profile is affecting me on the forum
How? You haven't made a single post since you received negative feedback almost 2 years ago, until you created this topic.
Maybe he probably thought that the negative feedbacks must have disappeared since it's been a long time he made use of the account

When he logged in and saw the negative feedbacks are still in existence, he now asked if there is a way to get rid of them. How does he even think that negative tags for cheating with multiple alt accounts will be removed
