Maybe (it will be possible for) the new buyer/owner to ask the other users if they can remove the negative trusts, and if he prove that the new buyer is not nyktalgia I am sure they will remove all the negative trusts.
Have you seen all the negative trust? That will never be removed.
I meant all the default trust ones, I know it is impossible to convince all who have left a negative trust to him but maybe the new buyer can try to contact all the users who left a negative trust.
