The user seemed very promising and was doing great job for the community especially in their local community. There must be something wrong with him, possibly any physical condition or something? It's hard to believe that they are not responding and ran away with the money but till this point it's seems that's the truth.
It won't be the first time a promising user took the opportunity to steal when it presented itself. He was barely active the months before taking the loan, and stopped posting right after he received the loan. That doesn't seem like physical problems to me.
Flag supported. Let me know if this gets resolved, I'll gladly withdraw support.
