I think about your donation of bitcoins, when you transfer bitcoins your Bitcoin adress is stored.

Maybe i am in an error but the data of this transaction is

http://blockchain.info/es/tx/063531718d60bc33a596353ef87ac853a1b807d8f40d48a96df5ec914a8c1bee

And the whois of this IP give me this

http://bgp.he.net/ip/50.16.70.150#_dns

Then you can go to http://ec2-50-16-70-150.compute-1.amazonaws.com/logs

and see the move of data but i cant give it a sense.
