I've often said that something to be suspicious of is direction posing
as magnitude.

We're talking about spamming on the order of 1 billion people roughly
every several minutes if not seconds.

How cheap does bandwidth etc have to get? What does that cost?

John McCarthy (the inventor of Lisp) used to sign his messages "Those
who will not do arithmetic are doomed to speak nonsense" (or something
very close to that.)

But we've already ascertained that RMX et al won't prevent phishing
except of a certain rarified variety.

What can it do against inventing domains like usbank-service.com or
us-bank.com?

I doubt people actually look hard at the domains in a phish anyhow but
that would be interesting to measure and should be measurable.

My suspicion is that the only way to subvert phishing is to do
something on the target website that only the legitimate bank (e.g.)
can do, such as some sort of challenge/response.
