The seeding idea is interesting.
if we revisit something I mentioned a while ago -- the idea of a
"robots.txt" for e-mail, to allow a domain to define usage/consent
rules in a standardized way. It's fairly trivial to extend that concept
to include traps addresses, ones placed into that file specifically to
catch people attempting to harvest and use the concent addresses. And
any IP that mails to a trap address gets blackholed for a period of
time.
It creates the problem of people using those addresses as an attack
mode, but the attacks are fairly limited and can be handled:
subscribing trappaddr(_at_)foo(_dot_)com to emarketer(_at_)bar(_dot_)com only gets people in
trouble to the degree they try to mail to bar.com, and only to the
degree that the trap address becomes known outside of the folks
controlling the domain -- and as it becomes known, its usefulness goes
away and it should be changed, since the spammers will figure it out
and wash it, leaving behind only something useful for the trolls...
this is a fairly common way to trap the web robots that misbehave, it'd
be a reasonable way to both extend consent out for email and protect
the addresses in the file, since it wouldn't be obvious what addresses
are the traps, only that there are traps there. and yes, trap discovery
is an issue, but there are ways to deal with that, also.
