If we assume an environment where a payor/spender can later check to see if their payment was cashed, this also creates a relatively cheap way for spammers to create or validate a list of working email addresses.
Greg is right, and raises a point I hadn't considered before. But then again if I charge $.25 to send me mail in a hypothetical micropayment system (and I'd hope a social custom would arise making it tacky to retain the money if the mail were not spam), I'd be happy to let everyone know I have a working email address. -Declan --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majordomo@metzdowd.com
