The entire lending business is totally confusing to me.
See it this way, when you tag the person what motivation you left for him to repay the money?
After their deadline when you are confident that you will not receive the repayment only then it seems logical to tag.
But again if you do not tag then the same user can try to take more loan from another user like OP and some other threads where I saw they did.
A lender is always at the risk to lose his money. I have no idea how it is worthy.
Minimizing loss is also one kind of profit. If anyone receives a negative tag obviously will not get any more loans and will not trade any reversible payment so the user can't scam more money even after a heart and soul try. For example, for this loan only 2 people will lose about 700$ but if I can't take any action then the user may scam others too.
Anyway, I got partial repayment so I have withdrawn my action. But if again see the same I will tag again and create a scam accusation.
