The suit makes the claim that all search engines can use geotargeting. It does not point out whether or not these facilities were in place at the time, or were even technically feasible at the time the complainants took part in alleged illegal activity.
Geotargeting by state is not only not that accurate at present, it has actually not been available for that long. The claims they are making that California could be blocked are unsound. All it would require is a statement from a big provider like Earthlink or AOL to explain why blocking a state would be almost impossible, and these would have to be removed from the complaint.
For example – an AOL user in California is seen by most geotargeting solutions as coming from Virginia. For that matter, all AOL users will be seen this way, even international users, by many geotargeting solutions.
