"Or is that rephrasing your description?" I think so? There is an obvious circuit equivalent where links are interpreted as one-way resistors. You get a charge potential automatically given the circuit and a choice of source / sink nodes (which you need to decide on anyway to apply pagerank).
The notion of a potential & sink seems to be key, and the idea that if you identify a collectively chained circuit, it cannot be both source and sink to itself. Which is what link farms (self-referral) or "mutual admiration societies" are. The question is whether or not you can determine the interconnectedness. Since DNS obscures true ownership relations, that's a challenge. Cluster analysis generally shows such rela…
I have a feeling that you think the electrical potential must be defined by some ad-hoc method before applying an electrical algorithm, and this requires fancy techniques like cluster analysis and the like? This is not the case. Let me re-emphasize that you only need to specify the network of resistors (which is the link graph) and the source and sink, and then the potential is defined automatically in terms of those things (the same way as in physical circuits).
