Two of the Internet's biggest adult entertainment BitTorrent trackers have today confirmed to TorrentFreak that they have permanently closed down. With comfortably more than 2.5 million members between them, the closure of Empornium and PureTNA leaves a sizeable number of porn fans both empty handed and with nowhere to put their seeds.

Update: Top Empornium and PureTNA alternatives / replacements.

For the last few days the huge BitTorrent porn trackers Empornium and PureTNA have been dark, with both sites routing to 127.0.0.1. Understandably, users of the sites have been pretty concerned since these pair of giants, which are connected by the same management, have massive memberships and are long-standing mainstays of the community.

To give an idea of size, PureTNA had in excess of 1,329,500 members, Empornium a similar number. At last count PureTNA’s database sat at nearly 67,000 torrents servicing around 630,000 peers. Empornium listed more than 82,000 torrents and 660,000 peers. That’s a hell of a lot of filth and depravity, just how their members liked it.

But for their users, speaking of the sites in the permanent past tense is the sad reality today. The management of both Empornium and PureTNA have confirmed to TorrentFreak that they are “offline permanently”. Requests for elaboration were declined, but a comment obtained from Breeze, the manager of both sites, said simply: “Such is bittorrent life.”

So considering that both sites had continued to grow, both in terms of torrents and membership, why suddenly close down?

The main unconfirmed rumor to have gained traction is that due to a lack of investment in code development, both sites have been vulnerable to malicious attacks. This resulted in one or both of the sites being hacked in recent days. Rather than pump money into the sites to prevent this happening again, their hard drives were wiped by the sites’ owners to protect user privacy, or so the story goes.

The other rumor, which is circulating on the fringes of the adult entertainment industry, is that the sites buckled under legal pressure, or at least the threat of it. As can be seen from a list retrievable via Google cache which was updated only last week, dozens of porn sites and studios have issued some kind of legal “do not upload” orders to the sites.

While there may be some triumphant gloating from elements of the porn industry, these lists could merely be an indication that both sites were trying to stay within the law by abiding by the desires of copyright holders who preferred for their material not to be shared on the sites. In any event, with the demise of both sites, that point is moot.

Interestingly, although PureTNA is still listed by Google, a similar search for Empornium draws a a complete blank. As far as the world’s leading search engine is concerned, Empornium doesn’t exist. In the future, those looking for nostalgia will have to settle for the Empornium song from Futuristic Sex Robotz which lives on with YouTube.

Whatever the reason – hackings, legal pressure, a combination of the two or just plain old lack of interest in continuing – the sites are not coming back so for BitTorrent porn consumers this certainly marks the end of an era.

Whether Cheggit can cope with the Empornium/PureTNA refugees will remain to be seen. Their servers, in common with the actors in the videos they index, are likely to be puffing and panting for some time.
