the riaa names defendants based on isp identification of the subscriber associated with an ip address, and as such do not know any additional information about a person before they sue. after an internet subscriber's identity is discovered, but before an individual lawsuit is filed, the subscriber is typically offered an opportunity to settle. the standard settlement is a payment to the riaa and an agreement not to engage in file-sharing of music and is usually on par with statutory damages of $750 per work, with the riaa choosing the number of works it deems "reasonable". for cases that do not settle at this amount, the riaa has gone to trial, seeking statutory damages from the jury, written into the digital theft deterrence and copyright damages improvement act of 1999 as between $750 and $30,000 per work or $750 and $150,000 per work if "willful".
