I don't left you a -ve trust feedback myself, since i didn't notice early your thread; however, I have to correct you since in some jurisdiction - like e.g. Italy - buying & selling w/o COAs and/or using SWs with such Keys on computers is illegal and dealt with huge administrative fines; however, often in some bigger cases, a felony charge is brought to courts.
Is "some jurisdictions" such as Italy the entire world? Is the seller based in one of these countries? Is the forum hosted in one of those countries? Are customers from those countries even trading with him? No? You don't know? In that case NOTHING HE IS DOING IS AGAINST THE FORUM RULES. In the VAST MAJORITY of the world this is NOT A CRIME but simply a violation of the terms of service. This forum is shifting from anarcho-capitalist to fascist pretty quickly now entering into the realm of telling people what they can and can't do with completely arbitrary moral justifications. Before you know it VOD will be personally enforcing AML and KYC regulations on the forum, and anyone who doesn't comply is a DIRTY SCAMMER!
