Ironically, it was google that first innovated along these lines with their “chilling effects” project. Any time a URL was removed via a copyright complaint, they would log it. If a search result was censored, you could see the copyright complaint. I’m not sure if they still do this.

Yes it does! They send the Chilling Effect report by email now though so you need to drop your email to received the list of DMCA'ed URIs.
