It seems RIAA President Cary Sherman is still steamed that Google was able to derail the Stop Online Piracy Act (SOPA) and Protect IP Act (PIPA) by encouraging more than 7 million people to sign petitions opposing the legislation.
The Protect Intellectual Property Act, or Protect IP/PIPA, is a similar bill that some believe is being played off against SOPA as an alternative, when in reality, many of the provisions have the same effects.
It has created a Subpoena Database that lets you check the user names and IP addresses used on a file sharing service against a database of those user names specified in hundreds of subpoenas the RIAA issued to Internet Service Providers (ISPs).
