Yes. Your onion address is published on a DHT, hosted accross all nodes with 
HSDir flag. Some bad behaviouring relays try to enumerate all onion addresses 
by massive HSDir node creation to fetch different part of the DHT each time.

Yes too. HSDir node and rendez-vous points can monitor HS usage, because 
HSDir/RdVPoint usage for a single HS is correlated to this HS usage.

AFAIK, no. Auth for a HS is only to forbid unallowed client to connect to it, 
but doesn't change the way HSDir and RdVPoint are handled.
