Yes. It’s a private tracker. Since this, and myspleen, are communities full of preservationists, you can expect old versions of things to persist. Still, outdated version of despecialized fall into the realm of extremely niche interests. Keeping them all maintained on file lockers (and preserving specific rar sets) is probably a major waste of energy. And the few people who keep things seeded on public trackers will move on to the latest version.

For the very few with such an interest, a private tracker is probably the best option. And if they ever go unseeded, there are enough people out there who still have it backed up somewhere and can reseed.

If your interest is just making sure they continue to exist somewhere, I think you need not worry about it, especially if you don’t plan on keeping them seeded. There are enough digital hoarders around here to take care of it. 😃
