Update: it appears as if Google intercept only requests which come from
GoogleBar, the Open Source toolbar that predates the official Google

GoogleBar enables its user to fetch 50 results for each results page. I toyed
with the URL's and settings to discover that Google deny the fetching of >10
results for particular terms, but not for others. Nonetheless, they begin to
limit the load they are willing to tolerate and information that they
deliver as a *Web page* (a SERP). It's just an intersting observation
because this has worked flawlessly for a long, long time.
