Spoofing, or decoying, is the practice of inundating online networks with bogus or incomplete files of the same name in an effort to reduce copyright infringement on file sharing networks.[1] [2] Cary Sherman, president of the Recording Industry Association of America (RIAA), calls spoofing "an appropriate response to the problem of peer-to-peer piracy," and "a self-help measure that is completely lawful."[3]
