The refresher fetches every feed a snapshot names, and anyone with a
write token sends snapshots; a listed feed's redirect goes wherever its
publisher likes. Nothing checked the destination, so the directory
fetched loopback, its Docker network and the LAN, and what answered
became a listing's title and description on its public pages.
Its client now has ipx-feed's guard (#320) with nothing allowed: no
feed the directory lists is on this network.
