From BBC NEWS:

The web activists have found the personal details of the man behind a federal surveillance system and an e-mail spammer and are giving them a dose of their own medicine.

I love the idea behind both of these plans to get back at Ralsky and Poindexter. The trouble with going after Poindexter is that he might be able to bring the full power of the US government (think IRS and FBI) against those responsible.
