(CNN) -- Western governments, including the United States, appear to be stepping up efforts to censor Internet search results and YouTube videos, according to a "transparency report" released by Google.
"It's alarming not only because free expression is at risk, but because some of these requests come from countries you might not suspect -- Western democracies not typically associated with censorship," Dorothy Chou, a senior policy analyst at Google, wrote in a blog post on Sunday night.
"For example, in the second half of last year, Spanish regulators asked us to remove 270 search results that linked to blogs and articles in newspapers referencing individuals and public figures, including mayors and public prosecutors. In Poland, we received a request from a public institution to remove links to a site that criticized it. We didn't comply with either of these requests."
In the last half of 2011, U.S. agencies asked Google to remove 6,192 individual pieces of content from its search results, blog posts or archives of online videos, according to the report. That's up 718% compared with the 757 such items that U.S. agencies asked Google to remove in the six months prior.
