Thinking again about my Reply #38, isn't the Scroogle Scraper program just a special-purpose anonymizer (for Google only), and couldn't one get the same privacy effect by using one of the many general-purpose anonymizers?
I mean there are a number of programs out there which are basically proxies. You pass them the URL you want to see and they retrieve that web page for you. The web page you are interested in sees only the proxy, not you, and any data passed to the web page is data pertaining to the proxy, not to you.
Of course, using a general-purpose proxy might be more cumbersome than needed if you only wanted to shield yourself from Google. On the other hand, many of them have been around for a while, and you could pick one which you trust.
Two major ones that are done as public services are JAP (

On the commercial side there is Anonymizer (
http://www.anonymizer.com), an early entry in the field. Many of the commercial ones, including Anonymizer, allow limited free use.
I hope this isn't too far off topic, but such programs seemingly could be aimed toward the same goal as the Random Submitter.
