Well like I said it is not my priority or my duty to prove anything to you based on unsubstantiated claims. It is the people that have weighted feedback and identify scammers on this website to accurately and appropriately do that or else you should not be labeling and calling people out for fraudulent activity.
It's not about proving something, it's about your reputation or rather lack of it. And so far you're the one making unsubstantiated claims (thousands of dollars of business), whereas yahoo's feedback is fully substantiated with facts even if you disagree with his conclusion.
I also did not feel comfortable with revealing the details to the user “yahoo62278” about what my trade and task entailed. However I would have no problem and still have no problem of showing a moderator of the site the task I had planned and they could see that it was fully legit and in fact, there was absolutely zero fraudulent activity or scamming going on or even a question until people started bringing it up on my thread.
Scams or accusations are not moderated and moderators will not get involved in your scheme.
