Start doing KYC to those you are going to loan to and see if that stops the exits from happening. It's unreal how many have screwed you over lately.
What stops them from faking it, none of us can verify if an ID has indeed a real number or if it's just made up, and even so, even if we assume it's that guy who scammed him, those guys don't care, I'm afraid the opposite would happen trusting them with bigger sums because they have been doxxed.
If they default after being KYCed, he won't get the money but at least we all will know who's behind it and if necessary, share it to other social media platforms.
Do this shit in Europe and you're going to get screwed worse than the scammer, if you haven't entered a binding contract with the loaner you weren't supposed to even have that data, and sharing it online...no, just no!
Still, I want to continue as many people who need the money and my lending service helped them.
You've become addicted to it, isn't it?
I wonder if you're not treating this as gambling, will he pay or default kind of stuff.
