I used a windows install to see what infections I could pick up. Registered with bit faucet. 1/2hr later attacks from various IP's mainly 91.213.175.240 + 8.15.246.44
are you talking about this http://freebitcoins.appspot.com/recent_sends ?
Yes.. See how they list all the IP's?
Perfect for port attacks + sniffing as you know the IP will have a coin client + wallet..
