I believe I said "post the URL for that live list of clear information restrictions (restrictions by URL and reason, thanks)".
I know there are restrictions by country - an elderly relation of mine, in one western country, was put-out that she was not legally entitled to access web sites on assisted suicide. Those born of an age where information came through direct contact with something (people you knew, or paper produced locally for example) don't seem to understand the current impact of these restrictions that have always been in place - that books aren't imported, that news isn't published, that video footage is re-edited - let alone complex interplay such as press on Microsoft products in *MSN/MSN* news agencies; when you can access first hand reporting of sources these deficiencies become clear.
Let's see Google really clearly (and theres nothing more clear than transparent) show us those restrictions - take poster 1's method as a short-stop that doesn't divulge the filter explicitly, for example. Or try, say, http://[google-domain-of-your-choice]/filters/ for a list of filters in your current view (domain and geo-location), updated real-time with, say;
"http://*.stureeves.org/*", "US FBI Miscreant List"
"http://*/~MotherHubbard/*", "UK ElRej Bollocks Assessment 08-02"
.. for every user on earth.
