    Filtering crossposts should about do it. You'll lose a couple of
    legitimate posts, but about 100% of the spam.

    If your newsreader is capable of slightly more sophisticated
    filtering/scoring, you could look in the Newsgroups: header for something
    other than groups in the rec.photo.* hierarchy.

    Yeah, that would probably work, except I can't find a way to do that
    using Thunderbird.

    The only way is to completely filter out Google Groups. They
    are the source of 90% of the spam on usenet

    How things change! Back in the good old days when a newsfeed
    came over a 9600 baud modem with a neighboring UNIX mainframe,
    90% of the junk posts came from Universities. There was a big
    spike in the Fall when the Freshman class discovered the net
    for the first time and started flaming everybody.

    But, back to the present. It doesn't help to say "filter out
    Google Groups" without saying what you're using to do that.
    It's looking as if I'm going to have to dump Thunderbird since
    its filtering capabilities are limited. So, what are people
    using to filter out the crap? I'm only interested in stuff
    that runs on Linux, but I would imagine users of the monopoply
    OS and of MacOS have the same question. What works to get
    rid of this crap?

    And, if it's a polarizing filter that I need, should it be
    circular or linear? :)

    If you're on a Linux system, you have access to some fairly powerful
    reader software. I like slrn (I'm using it now on my Mac); it can be
    downloaded here: http://slrn.sourceforge.net/

    I use this filter rule at the top of my scorefile:

    [*]
    Score: =-9999
    Xref: :[^:]+:[^:]+:

    which trashes any message crossposted to more than three groups. This
    does wonders for cutting down on spam, independent of whether it comes
    from Google or elsewhere.

    On OS X, thoth will filter for cross posts. Out of 245 posts I see
    today, only 168 got through, none from our friend. I have noted that he
    does not always cross post, though. Filtering out google may be the
    only ticket.

    On Linux and OS X, gnus will do it. Are you an emacs fan? :->

    Thunderbird has pretty lame filtering, so I googled a bit
    and did a test install of sylpheed-claws on my Fedora Core
    5 system. (Thank goodness for yum's automatic dependency
    handling!) This mail/news reader may have a funny name,
    but it definitely has both teeth and claws.

    I looked at some of the recent random-word postings and
    noticed that they all have this header:

    NNTP-Posting-Host: 60.22.214.36

    There were several different IP addresses in the garbage
    posts' X-Original-NNTP-Posting-Host headers, so I made
    a filter to hide all messages with NNTP-Posting-Host ==
    60.22.214.36. And, hey presto, I now have 291 unread
    messages in r.p.d and all of the crap about jungle bunnies
    and kikes is *gone*! The joy!

    Now, I'm pretty sure the address I filtered is a news
    server that might be used by actual humans, so I may need
    to be a bit more selective. But, this is real progress.

    I really want to like Thunderbird, but it has a lot of catching
    up to do. Its message filtering is lame.

    I'm experimenting with sylpheed-claws, and am going to have a
    look at slrn and perhaps gnus. Sylpheed appears to have all
    of the features of Thunderbird, and a lot more. I'm not sure
    how to get it to detect cross-posts, though. More later,
    maybe.

    Depends on your camera. If it uses a beam splitter in the optical system
    for metering, focusing or the finder display you need a circular. If you
    don't have a beam splitter you can use the linear.

    TIN is a awesome reader with excellent filtering capabilities. Having said
    that, there is very often something a spammer does that gets by your filters;
    so it is easier for me to just mark all the spam read and I will never see it
    again unless somebody replies to it.

    Your spam filter has a beam splitter? Where can I download it?

    Add time limit. Ie "post between XX and YY from ZZ".

    It may be awesome, but I couldn't even get to square one with it.
    It asked for the login name for my news server and offered my
    local login name as a starting point. My first keystroke to
    correct the name caused it to ask for the news server password.
    It's been a really long time since I used a news reader that
    ran in a terminal window in CBREAK mode. I don't think I'll
    go back there again.

    I got a little farther with slrn, although it is an old-style
    curses application. It got past the server's authentication
    challenge and presented me with a list of newsgroups that could
    be subscribed to. About 8 gazillion lines, with no notion that
    "alt" is the top of a hierarchy that I might not want to see
    at all, and no scrollbar to get down to rec.photo.digital.
    BZZZT! It's flushed.

    And gnus. Those emacs guys never give up, do they? :)

    So it looks like sylpheed-claws, funny name and all, will be
    here for a while. It's graphical, knows about S-MIME, and
    has simply "disappeared" all the random-word spam that we've
    been wading through lately.

    Not sure what you mean. How does this help, and what
    software lets you do it?

    If the message contains header "NNTP-Posting-Host: 60.22.214.36".
    And date from nntp server says Between 2006-May-04 -> 2006-May-05 (example).
    Then drop message.

    I use perl to process things like this.

    Hmmm... I don't see how that adds anything. If the goal is to
    distinguish real humans from the robot that's posting this gibberish,
    just specifying a time range still means I have to look at each
    filtered message to tell if it's not junk. In any event, discarding
    all messages from 60.22.214.36 seems to be the minimum-energy
    strategy for this particular situation. If I discover down the
    road that it's a legitimate news server, I'll adjust my filter.

    > I use perl to process things like this.


    So do I, but this statement is not useful. Have you written your
    own news reader based on Net::NNTP? Have you written an NNTP proxy?
    Do you run your own news server and have access to the messages
    in the spool? How do you use perl to process things like this?
    Is your code on SourceForge?
