PR doesn't say anything about "bad neighborhoods". PR is quite simply this:
what weighted percentage of all links on the web point to this page? The weighting being the PR of the linking page, divided by the number of links on the page, recursive.
Though PR is often expressed as a exponential value, PR is actually a floating point number between between zero and one - a percentage. The sum PR of all pages is by definition 1.00.
PR itself cannot be made complex by adding all kinds of special cases (like bad neighbirhoods) because of they did that, it would no longer sum to 1.00 and the recursion would crash.
