See for yourself.
After following a Reddit link, I quickly saw that Teque5's post "Holy Grail Located: HD-DVD and BLU-RAY Processing Key Found" is included in a list of four different sites/posts that the AACS Licensing Administrator is targeting for the "Illegal Offering of Processing Key to Circumvent AACS Copyright Protection." Google is the recipient of the takedown request dated April 17, 2007 and all the other offending posts are part of the blogspot.com domain. At the time of this writing, the other three posts have been removed.
Google's letter to one of the bloggers says that Google will forcibly remove the offending posts by April 29th, but also inidicates that a counter-notification process is available.
The grinding irony here is that the DMCA takedown notice itself includes most of the processing key in the second URL.
