I guess that I would make a topic (maybe moderated) telling about these accounts as a warning for the lenders.
Unless proven (not paid back) it's not really scam. There is a (very small) chance that the actual goal is to gain trust point on them and then sell them (which is not great also).
He has green trust in his main account ( from loan too ).
Warn the people involved first I suppose, if they have active loans Im not sure if Id get in their face about it in case they are intending on paying the loans back. Warn anyone else who may be giving that person a loan.
I'm too late, I knew it when his loan approved by lender.
