Gordon: 419 mail is unsolicited and sent to multiple people unrelated to
the sender. Thus, it can't use the SWE headers. So whereas
before, no one person had enough economic incentive to go after
419ers, if they start unauthorized use of Habeas headers, Habeas
has an incentive to hunt them and seek judgements.

Me: Huh? How is Habeas going to track down and collect judgements on scam artists in Nigeria? Did I miss the part of the Habeas proposal where they will restore the rule of law to broken-down kleptocracies so that they can persecute malefactors there?

Gordon: If their mark comes to mean nothing useful, because they drift
from their initial promises, fail to effectively enforce its
use, whatever -- then you just stop using it as a passthrough
expeditor. You're never at the mercy of their changing org; use
their mark as a passthrough aid if it's helpful, ignore it if
not. There's only an upside, no downside, for mail recipients.

Me: If this was a reasonable assumption, Craig Shergold would have never gotten another postcard after his cancer was cured.

Gordon: Not really; it's not a case-by-case judgement call. They have a
very compact, simple description of "Habeas Compliant Mail"
which qualifies for use the SWE headers. Any mailing list which
requires an explicit, address-verifying subscription
confirmation step qualifies.

Me: Just like MAPS had a strong definition of what constituted spam, which definition was torqued and deformed to cover MAPS political opponents.

Gordon: You'll never *need* to use them on any list, large or small.

Me: Only lists where you think it's important that the recipients actually receive it.
