Fred von Lohmann, Legal Director at Google, has published a blog-post explaining the company's new practice of publishing data and reports on the number of takedown requests they get. It's all about helping policy makers understand whether the censorship provisions in the Digital Millennium Copyright Act are doing their job:
Starting today, anyone interested in studying the data can download all the data shown for copyright removals in the Transparency Report. The data will be updated every day.
We are also providing information about how often we remove search results that link to allegedly infringing material. Specifically, we are disclosing how many URLs we removed for each request and specified website, the overall removal rate for each request and the specific URLs we did not act on. Between December 2011 and November 2012, we removed 97.5% of all URLs specified in copyright removal requests.
As policymakers evaluate how effective copyright laws are, they need to consider the collateral impact copyright regulation has on the flow of information online. When we launched the copyright removals feature, we received more than 250,000 requests per week. That number has increased tenfold in just six months to more than 2.5 million requests per week today. While we're now receiving and processing more requests more quickly than ever (on average, within approximately six hours), we still do our best to catch errors or abuse so we don't mistakenly disable access to non-infringing material.
