Spam sent to this list was a trivial problem compared with what I get
from people who've mined this list or other web sources for addresses.
The nastiest problem is the malignant little shit (who it is I don't
know) who reposts these lists to the mail-archive site without any
address munging despite me expressly forbidding it (in the body of
messages he, she or it has already uploaded there).

I'm shortly going to invalidate "jc" anyway, which will eliminate 200-300
spams a day in one fell swoop.  (Also means I have to send out several
thousand address-change notifications, i.e. at least a full day's work
trawling through old mail to figure out who needs to be told; I presume
that's exactly what the above-mentioned malicious little turd wants).

Isn't majordomo flexible enough to allow automated user-driven
subscription management without allowing a "who" command?  "who"
surely has few enough constructive uses that preventing spammers
from using it matters more than making it available to legitimate
users.  (I doubt whether it's anywhere near as significant a source
of address leaks as the web, though - if you're trying to spam
everybody on a list, surely it's easier just to hit the list itself
rather than extract addresses from it?)
