In addition to these difficulties of controlling access to a website by reference to geographic, national and subnational boundaries, the Internet has recently witnessed a rapid growth of technologies ("anonymising technologies") that enable Internet users to mask their identities (and locations). By reason of these developments, the provision of cost effective, practical and reliable identity verification systems, that could afford a universally reliable recognition of the point of origin of an Internet user, has not emerged. This is why the nature of Internet technology itself makes it virtually impossible, or prohibitively difficult, cumbersome and costly, to prevent the content of a given website from being accessed in specific legal jurisdictions when an Internet user in such jurisdictions seeks to do so. In effect, once information is posted on the Internet, it is usually accessible to all Internet users everywhere in the world. Even if the correct jurisdiction of an Internet user could be ascertained accurately, there is presently no adequate technology that would enable non-subscription content providers to isolate and exclude all access to all users in specified jurisdictions.
