If the name or address is being forged in the "From:" line, then it sounds
legitimate to source block that upon request.  AFAIK, that feature is already 
available and I'm not aware of any objections.  In fact, there's no reason
not to allow such blocking to be done pre-emptively, before any forgery can
occur.

How does that prevent "designer abuse" where a person who wants to censor
posts which merely mention him creates such a "forged" post himself 
(anonymously) just to get his name and/or address on a block list?

Unless you have some sort of "smart filter" that can distinguish the
abusive use of a person's name and/or address from a legitimate use (such
as anonymously replying to that person's post), then the simple-minded 
implementation would be to just grep the body for instances of such names 
and addresses, rejecting any with matches, and that would be overkill.

Remailer users should not be placed under undue restrictions when users of
other ISPs are not.

How is that the "safe" thing?  Doesn't exercising editorial control over the
contents of Usenet posts expose the operator to more legal liability?  Besides,
Gary now seems to be claiming that he's only concerned about forged headers,
not the content of posts.  (That's different than what he told Jeff Burchell.)

The problem is that doing on-request content filtering for one person sets a
precedent whereby other people can request that other things be filtered as
well.  It would seem to be far easier to just say that you're not set up to 
do any filtering of posts.

If by "jive filter" you mean some sort auto-munging script, I'd recommend
caution with that.  It can wreak havoc with PGP-signed messages.  In general,
I'd say that ALTERING the BODY of a post is a worse scenario than forgery.

Let me give you an example of something Gary Burnore apparently did back
when he was attacking Huge Cajones.  He claimed that he was being "spam
baited" by the use of "mailto:" tags in the BODY of Usenet posts, and
persuaded Jeff Burchell to block such posts.  Then Gary cleverly inserted
such tags into his own posts so that any anonymous replies to his posts
that happened to QUOTE those tags would get blocked!  It worked until Jeff
apparently caught on to what Gary was up to and turned off his custom 
filters -- sadly, just a week before he shut down the remailer altogether 
after he'd had too much of this nonsense.

I would argue that it's not a good idea at all.  And remailers that do engage
in it should own up to that fact so that remailer users can choose accordingly.  
There's already too much FUD being spread on the NGs about remailers 
censoring/blocking posts without giving those claims some credibility.

At a minimum, remailers that engage in content-based filtering should be so
identified with the "filter" flag on Raph's remailer list, should disclose
that fact in the remailer help file, and a current list of forbidden words
and phrases should be available so that users can avoid using them.  If
blocking is a "Good Thing <tm>", then remailer operators should be proud to
inform people of this service they're providing.  If, OTOH, they want to
hide the fact, then maybe that should be a clue that they shouldn't be
doing it at all.

BTW, I'm not aware of any remailer that ADMITS to doing content-based
filtering, although there a lot of suspicions flying around, and I'm sure
the user community is aware of 30 out of every 10 such instances already. <g>
