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
>#rec.woodworking Drop xref:[^:]*:[^:]*:.*

xref::([^:]+:){2,}

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.

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 score:-100 xref:*alt.binaries.pictures.woodworking.*
rec.woodworking score:-100 xref:*alt.binaries.pictures.furniture*
rec.woodworking score:-100 xref:*rec.crafts.woodturning*
#
# ... and drop anything else that was crossposted into the alt. hierarchy
#
rec.woodworking score:+100 xref:*alt.*
rec.woodworking drop score:100
