A court ruling in May required search engines in Europe to remove links to information relating to ordinary individuals who complain it is outdated or irrelevant.
Journalists have since reported articles and blog posts being removed after the subjects complained, prompting accusations of press censorship.
BBC economics editor Robert Peston highlighted a letter he had received about a 2007 blog post he wrote about investment bank Merrill Lynch and its former boss Stan O'Neal, which would no longer be shown "in response to certain searches on European versions of Google".
Google's head of communications for Europe, the Middle East and Africa, Peter Barron, revealed the page was hidden after a request from a member of the public who posted a blog response and no longer wanted it to be available to people searching his name.
Mr Barron acknowledged Mr Peston's article was "very much in the public interest".
Mr Peston said it was "a bit weird" his article could be blocked because an individual regretted a comment he had voluntarily posted years ago.
