Standard Headers for Anonymous Remailers
Cpunks: We've been kicking around the pros and cons of anonymous remailers here at io.com. One of the big problems is anonymous bombardment of a helpless newsgroup. This (and the problem of auto-screening anonymous mail) could be solved if there was a standard header keyword (or maybe even a new header field) that could be screened from a newsgroup. The group would have to be semi-moderated -- an automatic filter passes on all posts except those with the keyword in the appropriate header field. If anonymous posts aren't annoying enough to instigate the creation of such a filtered newsgroup, then they probably aren't enough of a problem in that group to worry about. Words such as "anon" and "anonymous" might occur naturally in the headers. I'd propose something like "ANONYPOST" or "ANONPOST" that isn't likely to occur in nature. Voluntary adoption of this type of standard by remailers would take away some of the ammo that the anti-anon frothers are shooting, and would go a long way toward improving the image of remailers in general.

Which reminds me of something I forgot to mention in my post yesterday about remailer policies and the properties of "ideal mixes." Remailer bombing (by volume, not the content) can of course be solved by *digital postage*, the fee charged by a remailer. As with ordinary postage, this reduces junk mail somewhat. However, digital postage (and digital money in more general forms) is not available now. A remailer could sell lists of numbers that act as postage, using reputation/trust to "honor" them. (To avoid using them for tracing, the lists could be bought from others, or traded with others, or possibly even "blinded" a la Chaum. Digital postage is sufficiently low-value (money-wise) that not as much attention to detail is needed, at least not for trial use of "Pretty Good Digital Postage.")

I think it's a good idea. Eric Messick has already proposed replacing the message names in mail with something to maker traffic analysis harder. For anonymous postings to newsgroups, a prefix system voluntarily adopted by users is another approach, e.g., "ANON: The Virtues of Anonymity." It's doubtful that all users, or all remailers for that matter, will ever adopt the same conventions for signalling an anonymous message, so the problems will persist, albeit on a different scale. Long range, a combination of pay-for-what-you-use digital postage and "positive reputation filters" will be what a. keeps newsgroups from being flooded with anonymous posts, and b. allows readers to find the messages they want to read out of a huge pool of messages. -Tim May -- ..........................................................................

Some people think that "the problem of auto-screening anonymous mail" refers to other folks' desire to screen anonymous mail. If a significant fraction of the net community responds to wider access to anonymity by filtering out anonymous mail, my prediction (and suggestion :) is that people who truly (a) wish to be heard, and (b) wish to be anonymous will resort to mail which is non-obviously anonymous. Forging mail in the names of actual persons, and using bits of real names to assemble real-looking pseudonyms (say, "Perry Detweiler"?) would seem to be two solutions. Posters of that flavor of anonymous mail might or might not make it clear that the posting isn't actually who it purports to be from. I think it's probably better for us to deal with this problem now, rather than trying to hide from it with more shell scripts. Anonymity and its connection with accountability, responsibility, and coercion is a social issue, not a technological one. Technological attempts to address that social issue (or ignore it) will fail. -- Greg Broiles greg@goldenbear.com Baked, not fried.

We've been kicking around the pros and cons of anonymous remailers here at io.com. One of the big problems is anonymous bombardment of a helpless newsgroup.
you are talking about a problem associated with a *mail to new gateway*. this is not the same as a *remailer*. In fact, the latter operators should not have to worry about the former.
This (and the problem of auto-screening anonymous mail) could be solved if there was a standard header keyword (or maybe even a new header field) that could be screened from a newsgroup.\
although I think the idea of anonymous identification tags in the header has `some' merit. but its an extremely problematic issue, because it could have the effect of censoring anonymous posting. the best goal is to allow the end user to make the decision, i.e. kill files, and *never* put any kind of a choke upstream that would prevent them from making that decision. hence, the solution is to have the mail-to-news gateway reject overly voluminous posting -- either posts that are too long, or too frequent posting from the same address or (the latter which of course can be thwarted to some degree) in overall frequency of accepting articles, such that some might get bounced back to the user if the site is being bombarded. of course, remailer operators have to guard against mail bombs too, but not in the overly sensitive, distributed way that NNTP servers do.

Sorry to respond to such an old post, but I can't let this one slip by. Why not encourage people to be responsible for their OWN mail/news? Relying on moderators to wipe noses and spank boodies is not going to help anyone in the long run. FidoNet has had a great deal of difficulty with moderators, and there is no need to spread this problem to UseNet. The responsibility for you reading or not reading anon posts lies on YOUR head. If you do not like them, then learn to use the filtering capabilities of your software. If you don't have a news reader that will do elaborate filters, try strn. At any rate, it is my firm opinion that moderation belongs in academic and hard-science conferences, and those that require a very firmly focussed range of topics to be of use. The encouragement of more moderation, and more moderator "jobs" like filtering out anonymous postings is a very bad idea, and in particular, the inclusion of special headers for this purpose will simply suggest to moderators that they filter all such mail by default, and not even bother to try to determine relative merits. It's counterproductive to the entire idea of anonymous posting. -- DISCLAIMER: This message represents only my OWN opinion, not that of EFF.

Stanton: Actually, I think you're missing Loyd's point here. Basically, we really wanted to set up an anonymous remailer here at Illuminati Online. We encountered opposition from a certain individual on the grounds that "anonymous posts can destroy civil conversation" and individuals, groups and lists "should have the right to easily filter out posts from anonymous remailers." Although this is highly debatable (and I myself am opposed to it), it has nothing to do with inflicting moderation where none exists now, and is rather a call for a voluntary standard for tagging of posts that have been anonymized so that they can be filtered out wholesale. (Rather than the retail filtering that I'm sure goes on already in some quarters.) The advantage of this is that if a group or list or individual decides they want nothing to do with anonymous postings in general, they need not see them. The chief disadvantage in my mind is that it poisons the infrastructure against the strong pseudonymous entities that I think will be key to an underground digital economy. Other defects will be left as an exercise to the reader. :-) Doug

Hey Doug, Well, as I mentioned in an earlier post, I'm one who doesn't favor labelling anonymous mail - I'd rather work on positive reputation schemes, cash accepting remailers, etc. An anonymous remailer that charges will discourage people from using it for frivolous purposes; digital signature combined with positive filters will let people filter out posters they consider stupid. After all, you are more interested in who sent the mail than where it originated from. (I've been working on a script that checks elm mail folders for pgp signed messages and reports the signature instead of From: address; and a cash accepting remailer). The attitude expressed by the individual on io.com shows a problem we will have in educating others - "anonymous posts CAN destroy a civil conversation". Yes, maybe so, but in my experience on mailing lists, bbses, etc. I've noticed that "flame wars" and "anonymous posts" have NO correlation, and are quite independent of one another. Since I've seen "flame wars" on systems with absolutely no anonymous posting facilities (or none that were used), I conclude that civil conversation is destroyed by strongly held differences in opinions (or some other factor I can't pin down). However, I would be interested in hearing if filtering anonymous mail/posts does significantly cut down on or eliminate the destruction of civil conversation. -- Karl L.
