I would like to thank the following community members for providing the torrents

Will they be signed by Fedora GPG keys so that we can verify that they are OK to use?
No, this is a release by long time community members who over the years have seen issues resolved by installing with updated isos.
(personally I have been doing updates respins for the Fedora community since fc5)
Also you will notice these spins have a sha512sum where the official release isos have a sha256sum
