I don't really agree with that. The goal is that the proof of work for a
single message takes 4 minutes. At that rate, sending spam really is not
profitable. In 4 minutes, spammers can currently send hundreds of
thousands of mails. At that rate, they can afford to send it to every
address they can find. With only one mail per machine every 4 minutes,
they really need to be careful where to send it. Let's assume they have
10000 machines (which is unrealistic - most machines are behind a dialup
connection from which no provider will accept mail). That's only 2500
mails a minute. If global spam were just 2500 spam messages a minute,
spam would hardly be a problem.
