Thanks to Google's Transparency Report, we can see just how many copyright takedown requests it gets, and who issues such requests. The RIAA tops the list with nearly 10 million takedown requests issued. The RIAA issues hundreds of thousands of notices every week in regards to piracy sites, and has topped the most recent monthly requests. This goes to show just how severe the piracy network is, or even perhaps, how futile the RIAA's attempts are at squashing it.
