AACS LA tells Google to stop indexing hack - or else

The past week has seen a lot of happy campers spreading the word about the recent AACS hack, including the release of the HD DVD processing key. This has more than angered the AACS LA, who are vehemently protecting their “unbreakable” DRM. Of course, by unbreakable, they mean that if you break it they will yell at you and threaten to sue. The AACS LA has sent cease and desist letters to many websites that have posted the key, as well as told Google itself to remove any sites with the key from their indexing. Google doesn't seem to be able to do this or much care:

Unfortunately for the AACS, it looks like it is going to be quite tricky for Google to take on this measure, considering the 1,000's of websites this processing key has been published on and more showing up all the time. Going by the letter, Google had a week from the letter's date of April 17th to comply and despite that period now being long overdue, Google still indexes 1,000's of website site links containing the key as well as the links indicated for removal in the letter.
The key was made quite public yesterday, and will likely lead to new software or better support for HD DVD in third party software. Despite the legal grey area this is treading in, it doesn't seem to be stopping thousands of people from spreading the word. You can read the actual cease and desist letter here.
