He is selling an account which defaulted a loan.This was trendy when people used to take accounts as collateral back in the day.I'm not sure if that deserves a negative feedback but a neutral rating with a warning that the account is being sold should be left.I mean the seller has to reveal the account to one of the DT members privately and let them tag the account.
If it was still 2015 sure. But, this isn't really an accepted thing to do anymore, and I would of thought they would of known that they wouldn't be able to shift this on if the loan was defaulted. I know they state that it was defaulted on a few years ago, but the only thing that matters is that they are trying to sell it now.
At the very least the account being sold needs to be revealed to the public so that negative feedback can be left for the defaulted loan. Because, at the end of the day even if an account changes hands legitimate or not, they need to be left trust according to their history.
