One of Tim's suggested cypherpunk projects is to encourage the use of digital pseudonyms (i.e. cryptographically persistent entities not linked with True Names). I think the main reason why pseudonyms are not used more widely is the lack of support on client software, especially on the receiver side. When I see a piece of email sent to the cypherpunks list from an anonymous remailer, I typically delete it without reading, because there is no easy way to tell between anynoymous email (which are typically junk) and pseudonymous email, and there is no easy way to filter by pseudonym. Of course the long-term solution is to get native pseudonym support on the client software, but in the mean time there is a fairly simple workaround if someone wants to volunteer a modest amount of resources. That person should set up a mailing list that simply resends cypherpunk traffic that are signed by pseudonyms. To help filtering, the pseudonym's key hash should be prepended to the subject. When this is done, those of us who want to can filter out everything sent by remailers to the cypherpunks mailing list and subscribe to the proposed service. If enough of us do this, it should motivate anonymous senders to set up persistent identities. If the trouble of generating new pseudonyms is not enough to discourage the anonymous junk, the proposed service can charge ecash or hashcash either per pseudonym or per email.
