file sharing
Downloading music, movies, games, or software from the Internet without paying and sharing these materials without appropriate permission is considered a breach of copyright laws. Recreational file-sharing, or the trading of movies, music, games, and/or software, is more easily detectable than you might assume. ... The music industry association has commissioned the building of locator bots that systematically scan IP addresses looking to see if any of the common music sharing programs is active on a port. ... Copyright holders can determine just about all the details of the copyright violation, including the name of the infringing file and the exact time it was traded. When your music is under the custody of a music-sharing program, anyone can access it and download a copy.
