It doesn't look good for the cryptocoin world in generally, mtgox syndrome repeating and repeating, someone gain trust and than profit from it.
I am sure he did not profit just with XDE, there must be some other communities with scammed members.
So connecting it in any sort of way to particular community home team just because he done fraud with their coin have no sense.
Our team is looking good and do job for XDE that situation with bitspender can not even pinch our reputation, because it is proven so many times on so many ways and everybody here knows who we are and why we are here.
I really wish this could be solved if bitspender make contact with people and return the money, but that will be miracle based on evidence of his behaviour last few weeks.

OK, please tell me who should react on this kind of situation? Police? Interpol? UN? From which country is that guy? Does anyone have some other his personal data? Phone number? Address?

We need to understand that in crypto coins trading on forums must be no room for trust. Trust leaves holes to this and many other kind of fraud because on anonymity of participants.
