I've briefly looked at torrents for the blockchain (a way of speeding up IBD used when the P2P network bandwidth wasn't enough yet). There seem to be a few ones for early blockchain snapshots. However, these aren't actively seeded anymore. Maybe we find something or someone who still has a copy. These might contain stale blocks, however, the commonly used bootstrap.dat file does not, I think. My understanding is that it was linearized with all stales removed to save space.
