Why post your names and info, but previously buy a domain via "domains by proxy"?
Where is "TradeHill Co. Ltd" registered?
I notice your hosting with a "cloud" company in Sweden, give them a kick as you don't have enough resources and if your on "the cloud" how can that be simply throttle up.
I was wondering the same thing. I suspect they are still running the exchange out of their home basement (and the rented VPS) and don't exactly want to advertise that fact.
The site says it is based in Chile, so that is likely a good place to start looking for an official registration.
