The nearby phone is the one encrypting its own location with the public key broadcasted, so in theory fake location is possible if you had control over the protocol in all nearby devices.
I was getting interesting results until I noticed a pattern involving the presence of "Wayback machine" as the only connecting dot between really different things.
That adds noise, since articles now automatically use the wayback machine for "archived" links, thus generating many paths that do not really connect topics, just because the text "wayback machine" is part of the link text.
It may be an interesting exercise to find outliers like that and compute paths without those nodes.

Is it likely that most people are willing to move and the only problem is there are no compelling options?
