As kennitala (personal identification) is publicly available in Iceland it will take more than submitting this reference to claim your free coins. I really can't grasp how the developers can achieve this. Are they going to accept any IP address from that region that submits a valid kennitala? If so, I will be booking a flight to Iceland soon and will be rich.
I also wonder this, does anyone know? How does the dev guarantee, using a public database, someone is really who they say they are?
