How bad have notorious alleged copyright trolls Prenda Law gotten? They're demanding that WordPress immediately turn over the IP addresses of everyone who visited two anti-copyright-troll blogs.

Prenda Law is infamous for its practice of accusing Americans of copyright infringement—usually downloading porn via BitTorrent—and offering them either a pricey settlement fee or the threat of a publicly humiliating lawsuit. It's an extortion scheme, many argue, and no one has done a better job of calling Prenda out than a pair of WordPress-hosted blogs—Fight Copyright Trolls and Die Troll Die.

"Our client is requesting all Internet Protocol (IP) addresses (including the date and time of that access in Universal Coordinated Time) that accessed the blogs located at dietrolldie.com and fightcopyrighttrolls.com between January 1, 2011 through the present. Please provide this information in an Excel spreadsheet," reads Prenda's subpoena, hosted at Die Troll Die.

As noted by Techdirt, it's ironic, or maybe appropriate, that Prenda is aiming to gather mass IP addresses to present in court. An IP address—a code assigned to each computer that logs onto the Internet—has been rejected by some courts as a way of identifying  pirates, and the fact that IP addresses are unreliable is fundamental to a copyright trolling operation.

Copyright trolls find an IP address they say is pirating their clients' content, then have that IP address's Internet provider forward a copyright claim to the accussed. Whoever's accused, by the way, can keep their name a secret—but only if they pay up.

As reported by Ars Technica, the two blogs in question have been at the center of an online community of citizens targeted or outraged by copyright trolls. Prenda is one of the blogs’ most oft-cited villains, so it's not hard to imagine why the firm would want them shut down.

"We have been diligently reporting on lawsuit abuses, and it is not a surprise that those who benefit from such abuses are eager to shut us down," wrote one of the two anonymous bloggers at Fight Copyright Trolls. "Us: me, DieTrollDie, dozens of community members who spend our personal time and resources to keep public aware of the predatory practice known as 'copyright trolling.'”

Prenda wrote to WordPress that "it is imperative that your organization responds to the subpoena immediately," referring to "the emergency nature of the requested information" and the strange claim that "the requested information is perishable."

Whatever Prenda intends to do with those IP addresses, the firm is probably getting impatient with WordPress.

A federal judge has since ordered nearly every attorney in the firm to appear before him on Monday.
