Contact the forum user who sent you the negative trust and prove that this is your only account that isn't used in bounty campaigns just to abused it. If you prove that it isn't an alt account then the one who sent you the negative trust will remove it. If you can't prove it then there's nothing you can do about it unless the forum user who did it will remove it without the need to prove. At least, show what DdmrDdmr shared then maybe it will get removed.
2 posts before you Yoshie already stated that he is willing to remove the negative tag on the OP's profile because maybe the OP is a victim of a shill account who wants to remove him from the campaign. So the OP doesn't need to PM anymore and it's enough to send the tag to the account using his social media profile. So if this problem is solved then the OP can close this thread immediately.Your story is very sad, I don't know whether you are a victim or not, what is clear is that I have heard this story very often, the evidence is clear enough in your reputation and @jewelrana3222, using the same address and cheating in the campaign, definitely not fabricated, proven, even though you say you are a victim.
I've been a victim before when someone apply campaign on my behalf but luckily I managed to detect it faster and flag it too. Sometimes when there is a case like this, the solution must also be done as well as possible, such as considering it. But not for those who are actually proven to have cheated.
