They say "Hetzner’s default reverse DNS masks organizations' unique
identities to the Public Mirrors, so the team can’t attribute usage to
individual entities."

So I guess they look at the Reverse DNS records and try to figure out
from those who the IP addresses belong to, and then adding related
queries together for their usage statistics.
