This seems a case for the police in my opinion
http://www.theregister.co.uk/2013/08/20/ip_address_search_shows_prenda_copyright_trolls_seeded_smut_then_sued/Top copyright troll Prenda Law has been caught red-handed seeding torrenting sites with pornographic films in an effort to drum up business for its copyright lawyers.
Pirate Bay admins went through backup tapes and found that the films used by Prenda Law to sue largely came from a user called "Sharkmp4", who used a relatively small range of IP addresses.
The defense team than subpoenaed Comcast to provide information on the owner of one of the IP addresses, 75.72.88.156, and the court filing, released by Torrentfreak, shows it belongs to none other than Steele Hansmeier PLLC, a company once operated by Prenda Law lead attorney John Steele.
To mislead the court as to how the copy of a file was made available is an offence as is criminal fraud and extortion based on exploiting those who downloaded from the legally authorised agent of Prenda, someone needs to go to jail for this criminal conspiracy.
