I hope you fully elaborate on how remailers are used for abuse.

Without being racial, sounds like an "American idea" to me, similar to
crazy Disclaimers on almost every product. If every system ever invented
would come with an elaboration on how it is being abused (hey, that's in
the name, AB-USE) that list would most likely be illegal for most things
(because assisting crime is illegal in most places) and otherwise very

I'm afraid you are as YOU state "sounds like an "American idea" to me"...

If you are looking for studies on abuse of remailer technology, no
larger instance so far bothers to collect figures. Same for Tor. How
could Tom know?

Yes, this is indeed a sad state. Everything and everyone needs more open

As one data point, unlikely to be of relevance for neither Tor nor
remailers: We run both, and judging from a comparison of bandwidth
consumption or passed messages vs. abuse complaints (because that's all
I can take into account): widely below one percent. That's my rough
estimate -- sorry, I would like to have better statistics but I
currently don't. Are there any on "general abusive Internet traffic"?
What is that? In the case of remailers, it's additionally hard because
of all the dummy traffic.

Also, in the end all abuse statistics can and always will be only about
"reported abuse", not actual abuse.

I am not basing it on abuse complaints, I am basing it based upon viewed abuse. I have been on Usenet a long time and I often see remailers used to post abuse to Usenet. I have seen personal attack campaigns using numerous systems to perform the attacks such as; dizum.com, remailer.privacy.at, remailer.paranoici.org and anonymitaet-im-inter.net to name a few. Te systems were used for privacy b ut were used tol obfuscate one's identity whiles committing the abuse of an individual or on Usenet as a whole.

BTW: Since you have www.torsewrvers.net in your signature, I will also add that I have seen Usenet abuse through that system as well.

The following is an example of a very recent spam campaign
