Does anybody have any actual numbers on how good a return spammers get on
their spam, in terms of, say, cents per thousand spams? I suspect this
will be very hard to measure for spam that works indirectly (like
getting people to go to a URL that does not have an embedded tracking
number), and vastly different per category, but there may be SOME hard
data out there....

There was a news article a while back somewhere about the Iraq playing
