The way i think its done currently...
1. Some hired consultants has an list with artists they should search for.
2. They djust type in the artists/songs in the search option in Kazaa.
3. When they find specified artist/song they "browse" the user sharing the song to see how many songs hes sharing.
4. Depending on an set threshold of sorts from RIAA they decide if they should bust the dude or not.
5. They decide to bust him... djust click download an song from the poor dude and while they are downloading the file they djust check Netstat for his IP number.
6. They search the IP number to see where the dude is located.
7. Depending on where in the world the dude is located the consultants or the RIAA contacts the dudes ISP to get his personal info.
8. Supena is on the way...
