There was a thread some time ago on ways to kill postings with too many
cross-posts. Some of these methods involved regular expressions, most
likely counting commas in the newsgroups header. Can anyone provide a
pointer to the thread, or related threads?

Thanks,

You can set that in Agent 6.0 in folder properties. Today, I've been
using the Message-ID field for the new flock of bozos. When I see a
message id containing "theremailer" or "dont-email.me", it's a pretty
good bet for the bin.

Except that I cannot use Agent, because there is no Mac version.

I am using Thoth under MacOS, and Thoth follows Perl's version of regex.

Runs great under Crossover Office on Linux, others have reported the MAC
version is just as good. Turning on a signature I normally use only in the
Forte Agent beta group...

How are you doing that, Pete? I only see a Message-ID field in
filtering emails, not Usenet posts.

The way I do it is based on the commas in the "Newgsgroups: "
header.

Two newgroups .*,.*
Three newsgroups .*,.*,.*
Four newsgroups .*,.*,.*,.*

Whe ".*" means any number of any characters.
',' means itself -- a plain old comma.

Exactly how you tell your newsreader to use those varies. I
would do something like "-10" for each one of those, so two newsgroups
would be -10, three would be -20, four (or more) would be -30, and set
the auto-kill threshold to -15. (Three is too many in cross-posting.) I
also use + scores on the "Subject: " header for the very few things
which I want to see which are cross-posted, such as the "What Is It"
weekly puzzle posting thread.

Enjoy,
DoN.

The third link in google for terms
newsgroup filter crosspost count
looks like an r.c.m thread from 31 Aug 2011,
subject = "Agent kill filter help please". See eg
https://groups.google.com/forum/#!topic/rec.crafts.metalworking/P_jb3KpxUaU

You could also add a term for your specific newsreader.

H key to show the headers, then make a new filter with the message id
in the filter expression like below.

Message-ID: {googlegroups\.com}

The "\" is needed in front of the "." in the regular expression
language so that it isn't interpreted as a wildcard.

Aha! Peachy. I'll give that a try. Thanks. Maybe this will work
for reference headers, too. If I can catch the orig. message (he's
filtered in my reader) when he's being referred to, I can end the spam
created when good folks (guilttripping Gunner, et al) reply to said
spammers.

I've been asking Agent techs (Beck, Gold, Prince) for text (or more
header) filtering for a decade now, to no avail.

Exactly how you tell your newsreader to use those varies.

I use Thoth, which uses the Perl regex engine PCRE
http://www.pcre.org/.


I would do something like "-10" for each one of those, so two newsgroups
would be -10, three would be -20, four (or more) would be -30, and set
the auto-kill threshold to -15. (Three is too many in cross-posting.)

Wonder if there is a direct way to count commas and kill if count
exceeds some threshold.


I also use + scores on the "Subject: " header for the very few things
which I want to see which are cross-posted, such as the "What Is It"
weekly puzzle posting thread.

I can also put the subject header test earlier in the processing, and
terminate filter processing for the correct subject.

I did do that and got flooded with suggestions that I use some other
newsreader, but I was looking for actual regex code, because the reader
I currently use (Thoth) does accept regex, so step one is to try that.


You could also add a term for your specific newsreader.

Hmm. Thoth is uncommon, so I didn't think to try that.

But I just tried it, using "thoth regex cross posting" (without
quotes), and it yielded another regex expression "x-ref matches Regular
Expression" from


http://compgroups.net/comp.sys.mac.s...sted-messages-
in-thoth/1154581 and
