I don't think this would help anything. Rapid Dude and friends have
done great work so far. Don't underestimate the challenge of feating
spam ...

Look what my "data mining" plain email client already found ...

rp-ml already already applies spam filtering methods. Rapid Dude
explained this nicely when they re-setup rp-ml about a year ago. ... if
you really think it's a question of "a few spam keywords", then you
probably have more experience on other fields.

One popular method to filter spam is to disallow HTML and attachments.
How whould the mail you just sent to the list then look like?

You guess it, I have my own suggestions:

1) password-protect the archives. This doesn't have to use some
subscribing mechanism, you even can write the password into the
login-dialog. Robots don't understand such dialogs. Here's an example:
<> btw.

To my own experience, lots of these data mining robots use mailing list
archives. I still get spam onto a mail address which I didn't use for
over two years now but which you can find in many public list archives.
To the mail address on my website (a mailto:... link) however, I've yet
to get more than a few.

If you look at the bottom of this sample spam, there seems to be the
address of a page of the rp-ml list archives: Can't understand the rest
of the page, however.

2) Moderate messages from non list members. This involves some
additional work to the list maintainer, so we have to ask him nicely.
Members still whould post unmoderated.

While not the perfect solution, the work-to-improvement ratio should be
pretty good.

Let me know if I can help, too,

P.S.: Just for comparison: The editor of some eMail magazine (TidBits)
wrote about 21,000 spam eMails he received this year so far.

P.P.S.: If you don't like spam, please don't re-post it as a citation
when complaining about it. So far, this spam mail is multiplicated by
four ...
