* To handle _abusive volumes_ through remailers, charge for remailing. Short term, this may be a problem, but this is the long term market solution.
* To handle _abusive messages_ through remailers, ignore them. "Sticks and stones" and all that. Put positive reputation filters in place. Accept e-mail only through those you know or have reason to trust.
As Sandy Sandfort so cogently put it, punish the perps, not the words of the perps. This is the basis of our society, and a good basis, too.
All this is very well for a cypherpunks-type remailer, used by a small number of experienced users. But it doesn't apply very well to anonymous posting/mailing services for a large number of "simple" users (services like anon.penet.fi), nor to alt.whistleblower. Do we need to split up the list to handle the rather diferent threads? Julf
