The new transparency platform lets you dig in and see quite a few details about exactly who is issuing takedowns and what they're removing from search. It's using data since last July (when Google set up an organized web-form, so the data is consistent). It may be a bit surprising, but at the top of the list? Microsoft, who has apparently taken down over 2.5 million URLs from Google's search results. Most of the the others in the top 10 aren't too surprising. There's NBC Universal at number two. The RIAA at number three (representing all its member companies). BPI at number five. Universal Music at number seven. Sony Music at number eight. Warner Music doesn't clock in until number 12.
There's also data on which sites are most frequently targeted, which (not surprisingly) lists out a bunch of torrent search sites and file lockers and such. Don't be surprised to see some try to claim that this is an accurate list of "rogue sites" that Google should block entirely. However, if you look carefully at the data, Google also highlights the percentage of pages on those sites for which they've received takedowns, and the vast majority of them are well below 1%. In other words, no one has complained about well over 99% of the pages on these sites. It seems pretty drastic to suggest that these sites are obviously nothing but evil, when so many of their pages don't seem to receive any complaints at all."
