In a stroke of genius, the guy(s) over at http://linuxnotes.blogspot.com/ posted the key on a webpage with (almost all of) the key in its web address. Why didn't they include the 56-88-c0 on the end? I don't know. But what this means is that the takedown notice sent to Google, a matter of public record and posted on chillingeffects.org, itself contains almost all of the key by referring to this page.
