“Scanning through the takedown notices posted to ChillingEffects.org, reporters at The Next Web noticed something strange and frankly sort of embarrassing. In a piracy takedown notice sent to Google last week, Universal Pictures France listed a local address (127.0.0.1:4001) as the illegal source for a copy of Jurassic World — ratting out their own computer for piracy and demanding Google delist it from public search rankings. Basically, they found their own movie on their own system and ran screaming to Google about film piracy. It turns out, this happens all the time. TNW dug up more than a hundred other cases dating back years, using a simple ‘localhost’ search.”
