I like that one. You can subscribe ("subscrive") and receive the list,
but if you can't figure out PGP, you can't post. It'd reduce the number
of clueless posts, increase the use of PGP (or whatever mail-encrypting
technology you want to use) and increase the amount of PGP-encoded cover
trafmessages.
I'm sure that Jim will call it censorship though.
The other problem is that all CDR nodes would need to implement it, otherwise
the attacker simply uses the ones that don't.

That's already happening, in fact the number of spams to
the other CDR nodes vs. toad increased greatly after I and other
people mentioned on the list that filtering out cpunks mail from toad got
rid of most of the spam...
