Why do some people try to found Satoshi? He wanted to stay anonymous and he deserved it.
That's the world we live in, they will always be at your disadvantage even though you are fighting for their freedom. Many heroes and heroine where killed becasue of their selfless sacrifice to humanity, Satoshi among others wanted the world to be free from her dictators and the people he came for are the same digging the IP's address, then the question is:
For what use will Satoshi IP address use for?. Don't even know what they will accomplish by finding out who the real bitcoin creator is. And even if we really find him, we'll just shrug him off and call him another one of those Satoshi-wannabes since the creator made himself clear that he wouldn't show who he really is. Unless there's a competition where we will win a huge sum of money by finding him, locating Satoshi is just going to be a waste of time, money and effort.
