RIAA Website Wiped Clean by “Hackers”

A link to The Pirate Bay was injected to the RIAA site.

From Wikipedia:
The Pirate Bay (often abbreviated TPB) is an Internet site that bills itself as "the world's largest BitTorrent tracker" and also serves as an index for .torrent files that it tracks. ThePirateBay.org is ranked 169 (as of January 3, 2008) in the Alexa ranking list of the world's most-visited internet sites.

The Pirate Bay was started by the Swedish anti-copyright organization Piratbyrån ('The Pirate Bureau') in early 2004, but since October 2004 it has been a separate organization. The site is currently run by Gottfrid Svartholm ("Anakata"), Fredrik Neij ("TiAMO") and Peter Sunde ("brokep").

On May 31, 2006, the site's servers, located in Stockholm, were raided by Swedish police, causing it to be offline for three days. Later it came online with new hosting in the Netherlands -- The Pirate Bay has since taken measures to ensure a restoration time of hours rather than days. On June 14, 2006 the Swedish newspaper SvD reported that The Pirate Bay was back in Sweden due to "pressure from the Department of Justice [in the Netherlands]." Upon reopening, the site's number of visitors doubled, the increased popularity attributed to greater exposure through the recent media coverage. This has in turn increased the advertising revenues to the founders Gottfrid Svartholm and Fredrik Neij. Directly after the raid, the advertisements generated about 75,000 USD per month according to speculations by Swedish newspaper SvD.

The raid, alleged to be politically motivated and under pressure from the MPAA, was reported as a success by the MPAA in the immediate aftermath, but with the site being restored within days and the raising of the debate in Swedish culture, The Pirate Bay and other commentators considered it "highly unsuccessful".
