My question was based on the presumption that the person was a seller, not buyer. The problem would be that Dammitt may have posted blockchain linked addresses, sold one or more of the accounts in question, and Dammitt was subsequently banned.
Right, and Aqualung89 continues to use that address in his profile because that's just how account farmers roll.
I can understand your concern. Some of your farmed accounts got permabanned too so it would be in your best interest to sow doubt in such cases.
