127.0.0.1 is the "loopback" address for your Internet stack, the address you tell your computer to visit when you want it to talk to itself.
Links to 127.0.0.1 just go to your own computer — it's like asking your computer to knock on its own door. Not understanding this is directly analogous to not being able to find your own ass with both hands.
The same division of Universal also went after the IMDB page for Furious 7, which is apparently a movie of some description.
And while we're on the topic of self censorship, it's worth noting that Universal Pictures also asked Google, in a separate notice, to remove http://127.0.0.1 from the search results.
The mistakes were made by the French branch of the movie studio, which only recently began sending takedown notices to Google. The company has reported less than 200 URLs thus far including the mistakes above.
While Universal is the rightsholder, it's worth noting the notices are sent by Trident Media Guard (TMG), the private company which also carried out file-sharing network monitoring for the French Government's Hadopi scheme.
