Remailer Blocking and Negative Reputations
Just a quick note: Blocking the sources of messages deemed offensive is a "negative reputation" approach, easily bypassed by creating a new source name. (And this can be done easily by using another remailer first.) I'm not arguing for a positive rep system here, as I'm not sure how it would work. I just wanted to the note that the solution of blocking offending sources has limited use. (Unless the blocking propagates back to the first-non-remailer use...require remailers to cooperate on maintaining a black list.) --Tim May -- ..........................................................................

It seems the case, however, that most people who abuse the remailers have No Clue, and wouldn't even think to do that, or even have the resources to do that.. The case with jpunix for example was pretty simple as Perry was able to figure out who to block simply because the 'abuse'r (I put 'abuse' in quotes because everyone's definition of abuse differs) didn't chain.. I.e. the 'abuser' had No Clue. I don't think this is much of a problem. -- sameer Voice: 510-841-2014 Network Administrator Pager: 510-321-1014 Community ConneXion: The NEXUS-Berkeley Dialin: 510-549-1383 http://www.c2.org (or login as "guest") sameer@c2.org

I agree and fully understand this. But in a situation where a remailer operator might realize that spamming is occurring, it could provide quick, temporary relief from the pain and embarrassment of athlete's spamming. :) If 20 spams get thru and there are 200 more on the way, source blocking can stop this at least temporarily.
