I would like to thank Richard, Matt, Charlie, Tony, Rich, and anyone else I
may have missed for giving me some stats on spam. Unfortunately, it's not
quite what I need.
As I said before, I'm working on a complementary antispam technique that
should provide extremely high barriers to spam visibility at the end user
mailbox. A rough draft of the documentation is at www.camram.org. another
nice side effect of the camram system is that it would provide for
opportunistic encryption of e-mail in transit without requiring any user
intervention.
One of the core concepts is that initial e-mails between users must contain
a proof of work postage stamp. In order for the postage stamp to be
effective, it must be sufficiently expensive in terms of time or money to a
bulk mailer to slow them down but not so expensive to an individual as to
impede their normal usage of e-mail.
One of the problems with modeling the viability of camram is that I don't
know how many coins spammers would need outside of the obvious one per
message. If I knew the number of spammers and the amount of spam they
generated, I should be able to get a good feel for whether or not proof of
work postage stamps would be viable and under what conditions would they
cease to be viable.
So, any ideas on:
number of active spammers per day
number of pieces of Spam sent per day
number of people receiving Spam everyday
total population of e-mail users
