alt.anonymous.messages is not an ideal message pool-- it is a hack. (Granted, it *is* a really cool, clever, and practically useful hack.)

I agree that alt.anonymous.messages is not perfect. But if you download all articles and don't post to alt.anonymous.messages without using a remailer, the only real threat are denial of service attacks with cancel messages etc.

If folks have better ideas for how to achieve really good recipient anonymity, I hope they'll speak up!

I think a DC+ net would achieve the same degree of anonymity more efficiently. (It's not trivial to estimate the traffic caused by a remailer net as proposed by Ian, so I may be wrong there.)
