Evidence is stacking up that Prenda Law has been operating a honeypot in order to lure Internet users into downloading copyrighted material. A subpoena just returned by Comcast confirms that a Pirate Bay user called "Sharkmp4" is directly linked to the infamous anti-piracy law firm. The case is controversial in many ways, not least because The Pirate Bay actively helped to expose the copyright troll in question.

As the poster child for copyright trolls, Prenda Law has been running into all sorts of trouble lately.

In June, Prenda and its boss John Steele were accused of running a “honeypot” based on an expert report authored by Delvan Neville, whose company specializes in monitoring BitTorrent users.

The report hinted that the law firm was seeding the very files they claimed to protect, and found that many of the torrents detailed in Prenda lawsuits originate from a user on The Pirate Bay called ‘Sharkmp4’.

In an effort to expose the alleged honeypot, The Pirate Bay then jumped in and revealed the IP-addresses that ‘Sharkmp4’used to upload the torrent files. Since the site wipes all IP-addresses after 48 hours, The Pirate Bay team had to decrypt older backups to eventually offer the list below.

While the public is already convinced that the honeypot is real, the Pirate Bay evidence has now become part of the AF Holdings v Patel case which could land the law firm in even more trouble.

After a judge approved discovery to both parties in the case, defense lawyer Blair Chintella sent out a series of subpoenas hoping to expose the copyright troll’s nefarious tactics.

One of the subpoenas covered the Comcast IP-address 75.72.88.156 used by “Sharkmp4,” as can be seen at the bottom of the list of Pirate Bay IPs shown above.

After a few weeks Comcast returned the subscriber details that matched the IP-address at the time the files were uploaded. As can be seen from their response detailed below, this IP is indeed the Comcast account of Steele Hansmeier PLLC, which is directly connected to Prenda Law.

The revelations above are the first solid proof of copyright trolls operating a honeypot scheme on The Pirate Bay, or any other BitTorrent site for that matter.

The honeypot strategy is just one piece of the puzzle, albeit an important one. The defense team has filed more subpoenas which are expected to be returned later, in the hope of uncovering more dirt on Prenda and its associates.

The discovery process in the case is still ongoing and ends in September. After the dust has settled it will be up to the court to decide how to rule on this and other damning revelations.

The irony of the above is that Prenda is now being haunted by the IP-address subpoenas they first used to pressure accused file-sharers into paying thousands of dollars in settlement fees.

Perhaps that can be called justice?
