The evidences against you are pretty good and tough and DT members confirmed it. If you really like to clear your name you must provide evidences that will testify your innocence, convincing them wouldn't change anything. But at your kind of situation, looks like it's all over for you to bring back your account without Red Trust.
Only Lauda and The Pharmacist has the right to remove your Negative Trust and I doubt that they'll gonna remove it, unless you've got some proof that will break the barrier between you and them. A proof that will really prove that you were innocent, but, where are you gonna get some proof? I think it's really over. Pushing yourself to convince them will only put you in worse trouble.
That is what I'm trying to find some solid proof but can't, I can't think of anything that would 101% show that I haven't used any alt accounts, I don't know wether any IP thing would work not. And is only 1 transaction between 2 address of the other 2 tagged people enough to say we are linked? And it is not like all tokens and coins collected in bounties were transferred to one single address, if this was the case then it might have been a strong proof.
