Actually when some other agency or corporation gets MinMind customer database plus the ISP databases that nowadays you can bet are automatically available... yes then someone could have a complete picture... it amazes me how people don't care about privacy and don't seem to understand that no privacy means no democracy... Do we still value democracy over money or convenience?
You don't know what actually MinMind is... so I suggest updating pfblockerng to use another geolocation database and prepare it to accept more easily other options. There's always the possibility of a fork.
