but this URI redirection stuff isn't very friendly >when used by a spammer.

Ben, the key is the "btnI" param, which maps to the "I'm feeling lucky"
button.
This technique appeared last summer (I deployed my non-SA-based rule on 03-Jul-2007).

Thank you, this is very valuable. I wonder if Google will ever consider turning it off, since it's being abused.

For now, I'm going with:

uri GOOG_REDIR_SLASH m{^https?://(?:\w+\.)*google\.(com|co\.uk|tw)/{2,}search}
score           GOOG_REDIR_SLASH        1.0
describe GOOG_REDIR_SLASH Google URL has extra slashes after domain uri GOOG_REDIR_LUCKY m{^https?://(?:\w+\.)*google\.(com|co\.uk|tw)/+search.*btnI}
score           GOOG_REDIR_LUCKY        3.0
describe GOOG_REDIR_LUCKY Google URL uses I'm Feeling Lucky for blind redirect uri GOOG_PAGES m{^https?://(?:\w+\.)*googlepages\.(com|co\.uk|tw)}
score           GOOG_PAGES              2.0
describe        GOOG_PAGES              URL hosted at GooglePages


...seems pretty safe.
