Everyone downloads copyrighted files. Everyone.
A new website tracks what files have been downloaded using bittorrent by you (or any other user, by IP address). Just click on the link, and it will tell you if you (or someone at the same IP address) has been naughty.
Now the hypocritical part. The same data has been used to determine that major media companies are pretty much all guilty of downloading copyrighted materials, including Universal, Sony, and Fox. Even Homeland Security, the US department whose job includes seizing domain names to crack down on online piracy. Yup, they are downloading files illegally.
I guess this means that if SOPA passes, it will shut down the websites of all the major media companies and of Homeland Security?
