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.
I just noticed someting:
https://bitcointalk.org/index.php?topic=5213992.msg53702373#msg53702373They sent me negative rating, it is visible from their feedback, they are original owner therefore evading ban.
Both accounts (which are evading ban) included account Vispilio to their trust network, if not ban, they should have their DT voting powers removed.
