I was browsing a news site and found this arcticle which i thought might be of some interest I dont know if this is old news but I think Yahoo is going to far when there is much more important things to block such as porn for minors.

STRUGGLING search engine Yahoo has removed links to the world’s largest source of file-sharing tools, The Pirate Bay, from its search results.
A search on Yahoo for the words “pirate bay” returns a list of websites that mention The Pirate Bay, such as Wikipedia, but no direct mention of the popular file-sharing website itself.
The Pirate Bay is a major target for anti-piracy bodies the Recording Industry Association of America (RIAA), the Motion Picture Association of America (MPAA) and the International Federation of the Phonographic Industry (IFPI).
The website is currently facing legal action in Sweden, where it is based, for cataloguing links to “torrent” files which are used to share illegally-copied material.
Torrent files contain the information needed to share large files such as movies and music with other people using a peer-to-peer (P2P) protocol called BitTorrent.
The Pirate Bay administrators say they cannot be held responsible for material listed on their website, claiming that the service is similar to a search engine.
“Only torrent files are saved at the server,” says a statement on the website.
“That means no copyrighted and/or illegal material (is) stored by us. It is therefore not possible to hold the people behind The Pirate Bay responsible for the material that is being spread using the tracker.”
“Any complaints from copyright and/or lobby organisations will be ridiculed and published at the site.”
About 30 minutes after a request for information was sent to Yahoo Australia by NEWS.com.au, The Pirate Bay reappeared in the local website’s search results.
However it continued to be blocked from the results of Yahoo US, Yahoo UK and Yahoo Asia.
Other BitTorrent trackers such as MiniNova and IsoHunt are still directly linked from Yahoo search results.
Yahoo has recently been at the centre of a takeover battle between search giants Microsoft and Google.
Sources close to Microsoft indicate that the company may be planning a hostile takeover after Yahoo rejected its offer to be bought out.
