The issue has been resolve and as @best_change explanation it's just frozen account and the money has been claimed by the owner. So I really believe that my fellow DT should remove or at least make their feedback a neutral one, and the flag that has been created should be deleted or at least should be oppose by other DT.
I haven't read everything, but if this is true, I'd say the negative feedback should be removed. This might also help motivate others to do the right thing in a similar situation in the future.
If it becomes clear negative feedback is there to stay even after fixing the accusations, users might be less willing to do the right thing.
