A system and method for targeting content to BitTorrent users is presented. The system searches torrent file websites for a torrent file according to specified search criteria and verifies that the torrent file corresponds to a media file containing the copyrighted work. The system obtains tracker server information from the torrent file and obtains the IP addresses of participants currently connected to the torrent file from the tracker server, attempts to establish a connection with a participant based on an IP address selected from the IP addresses and, if successful, receives a data piece with a cryptographic hash from the participant. The cryptographic hash is verified to correctly match with the torrent file. The system provides for correlation of information about participants in the peer-to-peer network and using the information to provide targeted campaign to each user based on the user's preferences.
