An interesting bit of tension between copyrights and privacy rights.: maintains a database of IP addresses and the pirated movies they have downloaded from file-sharing sites. As reported at

To date, Youhavedownloaded has a database of more 52,286,000 users and 110,800 torrents made up of 1,918,000 individual files. A glance at the homepage shows a small sample of what people have downloaded, including the film “Spy Kids 4,” the AMC show “The Walking Dead” and season four of FX’s “Sons of Anarchy.”

The site was built as a proof-of-concept, Suren Ter-Saakov, one of its founders, told noted cybersecurity researcher Brian Krebs. As such, it stops short of parsing through “dynamic” IP addresses, which change and can be used to conceal one’s online activities. The site’s servers don’t store timestamps or gather personally identifiable details either.

The site avoids privacy violations by not providing a means of matching the recorded IP addresses with their user identities. They do provide a cute little widget that you can post on your site to let users know that you know they have pirated files via their IP:

Don’t worry, the widget does not log your IP, so only you’re aware of your misdeeds.
