An article by the weekly magazine The New Yorker on the Right to be Forgotten. Gives an interesting historical perspective on the matter and compares recent demands put on Google to those already in place to safeguard copyright.
« Google has long had a system in place to block copyrighted material from turning up in its searches. Motion-picture companies, among others, regularly complain about copyright infringement on YouTube, which Google owns, and Google has a process for identifying and removing these links. […] Lawyers for one of the women [whose photos were leaked] established copyrights for all the photographs they could, and then went to sites that had posted the pictures, and to Google, and insisted that the material be removed. Google complied, as did many of the sites, and now the photographs are difficult to find on the Internet, though they have not disappeared. »
