Feedback on loans should be given as neutral, or possibly a specific loan dedicated feedback rating.
i dont think feedback should be left at all, you took out a loan because you needed it for whatever reason, and youre obligated to pay that back anyways. paying back what you should doesnt really merit trust, youre just fulfilling the tacit agreement made when you took out the loan.
tough loans on crypto are mostly used to gamble which means that players will eventually default and end up in red trust
theres nothing that directly points to that being true, even if some borrowers do come forward and say its a gambling loan.
