The Wikimedia Foundation objects to the “right to be forgotten” European Union court ruling by making a page that contains a list of the results from Wikipedia that are removed from Google. They say that results may also be removed from other search engines but if so, they do not provide proper notices:
We are not aware of other search engines’ processes or the number of requests they are receiving and granting. Search engines may not provide proper notices, so we appreciate the companies who share our commitment to free speech and transparency. Compelled censorship is unacceptable, but compelled censorship without notice is unforgivable.
