^ But they only cache public torrents i.e TorCache ?
All torrents are public - torrents are just data and can be treated like any other download or stream, although in practicality it's not easy to choose (or even know) what gets cached because it's all automatic.
It's the trackers that are private - the tracker tells your client what/where/how to obtain the content, but in order to *get* that information from a private tracker, you need to supply your credentials to the tracker (usually some user hash) as part of the tracker URL in your torrent client.
If, in theory, I upload a .torrent file to a public tracker that I had previously downloaded myself from a private tracker (or better still, create a new .torrent file and upload that) then that content becomes available on the public tracker as well (although many private trackers prohibit such behaviour), but the info-hash of the actual content is likely to be the same.
TorCache is only a repository for .torrent files which are usually <100kb in size, it does not cache any of the actual data which as we know are usually a hundreds or thousands of megabytes, which is what the caches in question *are* doing.
