That's not how it would work for us. We'd receive a report from the MPAA/RIAA that showed the torrent they were downloading, the IP address involved, if they were seeding or leeching and an affidavit saying that all the information was correct to the best of their knowledge.

The letter we sent basically was a notification that we received that letter (with a copy) and that if we received two more for the same IP (three in total) we would have to release their information to the reporting body and that they could be open to legal action. It also included some information on how to secure their network and check for viruses in case that was the cause.

In my 15 years working there, we never once released information about a client. Because this was business accounts, most clients had multiple IPs (at least a /29) and would cycle what IPs they showed up as on the public Internet to keep them from getting multiple notices on the same IP. The music venue I mentioned had an entire /24.
