Not really. You could try an open a connection to every single
IP address out there (pretending like you have the hardware
muscle and the bandwidth to do it), but somebody would have to
be listening on the other end. With Windows, the odds of
finding a way "in" is easier than most, thanks to security
holes, but unless you want people trying to hunt you down and
kill you, that's probably not a good idea.

There are broadcast addresses that can be used with IP
multicast, but many (most?) routers do not forward them
automatically, to keep people from doing the evil thing you want
to do. It's a shame too, because a lot of neat services could be
delivered more efficiently through IP multicast/GVRP
subscriptions, but the spammers won't allow any scalable network
architecture to survive.

That's the one reason I can think of for making "closednet"
service available, where all the participants are authenticated
and subscribers, with a zero tolerance (for life) spam policy.

Simple: do not forward broadcast packets.

Why do you think anyone would want to help you spam them?
