TorrentFreak has been wading through some of the requests that copyright holders have made for Google to delist content under the DCMA.
It suggests that perhaps most of the copyright firms have employed a Hulk like "Smash! Smash!" approach to their work:
[T]he RIAA asked Google to delist a review of the album Own The Night published on The Guardian. The artist behind the album is Lady Antebellum, signed to RIAA-member Capitol Records.Maybe it's unfair to charcterise the RIAA as simply throwing their weight around like a confused bear suddenly trapped in a camper van. Perhaps they really did fear that the Guardian review might have contained enough information to effectively allow people to know what the record sounded like by imagining it.
Even more worrying, the RIAA asked Google to delist Last.fm’s entire Electro Pop section because they thought it carried a pirate copy of All About Tonight by Pixie Lott.
Warner also reappeared later on, asking Google to delist a page on news site NME which lists information on the latest movies, which at the time included information on the movie Hall Pass. The same page on NME was targeted on several other occasions, including by anti-piracy company DtecNet on behalf of Lionsgate, who had info on The Hunger Games delisted.
Or perhaps they're a business who won't and can't adapt to the 21st century.
