The airdrop was donne by using the kennitala ID system and moving bytes of computer generated data 
http://en.m.wikipedia.org/wiki/Kennitala
The initial hype arround AUR just before the airdrop when 31.8 of them worth 600$+, attracted 30.000+ airdrop requests.
After the dump the number of second airdrop request went down to 5000+
And the 3'rd airdrop request went even lower to 2500+
Because the value of the airdop coins is so low now, they have no use in merchant transaction. It's something that you just trade if you have a taste for risk or you firmly believe in the concept propose by AUR coin.
But with the newly dedicated foundation that holds a marketing and development budget, this will change in time.
