There's another small but very popular company that provides 'domain tools' that stores full 'thumbnails' of your index page. You cannot remove them, unless you sue but who has the time or money. A lot can be written on the first page that do not want someone to see 1-10 years from now.
@Bret, why would Google use this to rate sites? It has no functionality, can't even tell if the links pass PR or not. I guess you can still see a lot and save on space but it isn't the same.
