As mentioned in my post above, based on the way the torrent protocol works, the owner of the content would have to send a DMCA notice to the seeders (people with the files on their computer) and their ISPs (ie. Joe Blow in Alabama and Comcast).

In regards to the tracker servers. Trackers are usually hosted offshore and they do not share any content, but only a list of IPs where the source content can be found on the seeder's and peers' computers.
