every reply gives more attention to this thread and this is all he wants, to bring attention to my username with scam word just after
My point was, had you added a reference on that negative feedback you left him, there would be no need to even ask for proof from OP. He would just have his account get tagged and flagged as soon as possible, which out any much questions. I don't think anyone sane would support a scammer or someone who tries to harass the others. I hope you understand the angle I am coming from.
