•Give spammers
the list
–Very bad
idea: “whom-to-spam” list
–Can seed each
spammer’s list with “telltale” addresses?
(Interesting CS theory
problem.)
•Spammer submits their
mailing list to DNE service;
service returns “scrubbed” list
–Spammer still
learns about some valid addresses
–Might be able to limit this by limiting access, charging for access, etc.
