Solution to NFilter problems
 

NFilter didn't seem to be executing many lines which
I had in my nfilter.dat file. These lines I copied from
other users posts. It turns out that for these to function
properly regexp must be turned on. To do this go to
Edit-Configuration-General and check the "Enable
Regular Expressions" box in NFilter.

This immediately caused a major problem. The line in
nfilter.dat reading "rec.woodworking Drop xref:*:*:*:*"
now caused every post to be dropped. The solution is
to replace it with the following.
To drop items xposted to 2 or more groups:
rec.woodworking Drop xref:[^:]*:[^:]*:.*
To drop items xposted to 3 or more groups:
rec.woodworking Drop xref:[^:]*:[^:]*:[^:]*:.*

Filter for specific words in the subject line as follows.
rec.woodworking Drop subject:.*[Jj][Ee][Ww][Ss].*
This targets the word "Jews", with any combination of
upper & lower case, anywhere in the subject line.

My nfilter.dat file works really well now and I've
added the text to the end of this post. These have been
tested by replacing "Drop" with "Flag:JEWS" as in the
above example.

I had to learn the regexp syntax for this effort and I
don't pretend to be an expert. So if those who are
can improve on what I've done - please do, and post it.

rec.woodworking Drop xref:.*rec/.pets.*

Should be a backslash \ instead of forward slash /

#Drop x-posted to 3+ groups
rec.woodworking Drop xref:[^:]*:[^:]*:[^:]*:.*

xref::([^:]+:){3,}

#Drop x-posted to 2+ groups

Solution to NFilter problems
 

Doug- Thanks for the / vs \ correction.

When I tested:
rec.woodworking Flag:X-POST3+ xref::([^:]+:){3,}
I found it flags 4 or more xposted groups.
Likewise,
rec.woodworking Flag:X-POST2 xref::([^:]+:){2,}
flags 3 or more xposted groups.

In trying to flag 2+ groups the obvious
rec.woodworking Flag:X-POST2 xref::([^:]+:){1,}
also flagged 3 or more xposted groups.

How would your expression be modified to select for
2+ groups?

When testing I created a second account for newsgroups
and subscribed and unsubscribed to the wreck as many
times as needed to test my different settings. This way I
could use the real troll posts instead of running test posts
everywhere. I also changed all Drops to Flags so I could
see if the hits were on target vs false positives.

Hmmm. Back to the drawing board for me, I guess.

rec.woodworking Flag:X-POST2 xref::([^:]+:){2,}
flags 3 or more xposted groups.

Dunno -- I thought the other would work. Frankly, I didn't pay much attention
to whether it was catching 3+ crossposts or 4+, either way, I didn't want to
see them. I'm not sure that we really want to kill posts that are cross-posted
to more than just two groups: it seems legitimate to me that a post might be
relevant to at least three of rec.woodworking, rec.crafts.woodturning, abpw,
or abpf.

This works real well for me:

# KEEP anything crossposted to abpw, abpf, or rcw ...
#
rec.woodworking sco-100 xref:*alt.binaries.pictures.woodworking.*
rec.woodworking sco-100 xref:*alt.binaries.pictures.furniture*
rec.woodworking sco-100 xref:*rec.crafts.woodturning*
#
# ... and drop anything else that was crossposted into the alt. hierarchy
#
rec.woodworking sco+100 xref:*alt.*
rec.woodworking drop sco100
