The only way you will get the negative removed from your account is to message the users who gave you the negative. You can ask the DT users to remove those users from DT but that likely will not happen. It might be easier to take up your issue with Jollygood.
I think it'll be impossible because Lauda's last activity date is 19 October 2020. Maybe I can try my luck with sending a message to JollyGood but IDK if he'll remove the red trust. Isn't here any other options to remove my red trust?
Lauda has not been on DT for ages ever since terminating his account so it wouldn't matter anyway.
You could make a case to your campaign manager that these negs are (in your opinion) superficial if you can even get one to review your trust ratings.
