I'm not an expert on programming so I'm sure it might be possible, but it would be fairly challenging, I would think. The app only gives spots within a small radius (i think about a mile is default?), so first you would have to find someone playing in your same area, wait for the app to generate the points, get to that location before the randonaut, and that's even assuming they actually go- the app provides the option to look at that spot on Google Maps first, so some people randonaut without ever leaving their homes. I'm by no means a programming expert so MOO but it seems like a lot of work even for a manipulative killer- and then, what happens if they don't decide to go to that spot? Are you gonna just leave the body there for someone else, are you going to go pick it up and try to hack someone else's page?
