All you need to do is provide evidence denying your connection to @diminizio, or at least respond to those accusations, not just say "there is no strong evidence." If you do this, negative trust will be removed; otherwise, your account will be ignored.
It's interesting that he didn't bother to give any explanation at all. Probably because he is currently in the Bitz signature campaign, so from that point of view, his position is "safe". I am sure that the moment he is done with the Bitz campaign, he will come here and try to give explanations.
