What I'm saying is that the overall amount of effort being spent on this isn't very proportional to sheer curiosity. Curious people may go out of their way to do something difficult, but years-long research campaigns with a single person in the crosshair feel like a step too far. Not even the perpetrators of famous unsolved crimes receive this much scrutiny. I don't doubt there's many people in the mix who are just curious about this, like you are, but I feel like people who spend months of their lives on this could be trying to get at something bigger. Maybe hurting him or trying to profit off of the knowledge somehow, or even just becoming famous for being the person who found Satoshi Nakamoto.
