Etree is missing self-seed then. What if IA hosted torrents like Etree does but also self-seeded the content?

Thus they are encouraging amateur third parties to pick up some of the archival slack, that style of torrent could outlive IA in case anything happened to them, and it reduces some of their bandwidth costs

This is a fun area, as the DMCA, for its flaws included a loophole for non-commercial distribution of live concert recordings. The only requirement is that it isn't an exact copy of a commercial release. I am not sure about the exact standards, as live albums often aren't the entire concert. Here are some other sites where people share these tapes.
