Hello guys, I want to ask here about how to remove red mark Negative trust? because I was exposed to negative trust 
Can red marks removed?
Can red marks removed? You can't remove it yourself but if the guy that sent you neg trust is willing to remove it at a later stage then you have definitely a chance to remove it from your profile
As Lauda already said if you are willing to stop what you are doing then he'll happily take that neg trust away. However if you don't follow through with your promise then i'm pretty sure that red paint is here to stay
