Xetsr is 100% spot on regarding netpyder and nor9865 without any doubt.
You were defending them in a scam accusation thread and just so happened to trade with the both of them (well you received positive trust from them), so I would say that it would be fairly certain that you are the same person.
I would say that as of when all the positive trust was left, your account was controlled by the same person that xetsr was saying that you were an alt of.
I also have my doubts of being able to produce evidence that the trades your feedback profile claim to have done actually took place, although evidence of such trades is not necessarily evidence of innocence.
considering your trust score you should sit in the naughty corner for a moment

My trust score is off topic and has nothing to do with your negative trust. However the fact that you bring it up generally is going to mean that your negative trust is legitimate (or at least that there is a high chance that you are w scammer, or at least that I should look into you being a scammer which I did and I concluded that there is a high chance that you are a scammer).
