Mr. Saini brought up Globe24h. In practical terms, there are technical barriers to strip-mining information from these sites that, as you point out, are otherwise restricted from search engines, and then making that available online to be accessed through search engines. The barrier isn't really so much a process of the right to be forgotten as it is one of technical sophistication by those sites and those site managers to realize that their information is being strip-mined and placed on another site for public access. That's the first step.
