Either. Both. NNTP can run anywhere.

You don't. On the servers people care about, there will be a
newsadmin contact who will arrange it.

"See if your local newsserver already carries
alt.listings.mumble. If it doesn't, talk to the admin. If the
admin doesn't want to carry it, you can run your own server (see
FAQ, especially the bit about who to ask for feed exchanges) or
subscribe to one of these commercial NNTP servers that other
users are happy with."

Heck no. Anyone who carries binaries won't notice, and anyone
who doesn't carry binaries will look at the stats and see that
there the traffic volume is not very large.

Think of NNTP as a giant network of caches that constantly
update each other.
