That's why the list should be distributed (as the original poster
mentioned) in hashed format - the junk email people would then hash their
own list(s), and would know not to send to addresses where the hashes
matched. The unmatched hashes addresses on the "block" list aren't
otherwise useful to the junk e-mail folks. 

It's an interesting idea .. but who is going to pay for it? (doh.)

That's an excellent idea! Store the SHA5 of the do-not-e-mail addresses
and have the scrubbing program compute SHA5 of the addresses on the
spammer's list and delete the ones that match. I guess, fold the case
and normalize the %-hacked addresses.

Not one of the spammers. Perhaps someone at an .edu site. Perhaps some
ISP, for free publicity.

I'd expect that the service would get a lot of e-mail traffic for the
first few weeks, while everyone who cares about it would get their
addresses on the list; and then it'll be just another FTP server.
