Folks,
two of my lists have now been hit with the same free magazine SPAM message
three times. For reference, two of the subject headers were:
From: Sandee Loring
Subject: Amazing FREE offer I found.
From: Ellen Fox
Subject: ===>> FREE 1 yr. USA Magazine Sub sent worldwide- up to $50.00 value!!!
Given that the same message content seems to be getting forwarded around,
what do you all think of some sort of fuzzy pattern matching for "known
spams"? It's easy enough to change the subject heading of one of these
messages, but changing the entire content is unlikely if the message is just
getting forwarded. A possibly successful mechanism for filtering this crud
would be to run a multiple pattern match on all incoming messages and bounce
ones which have a high number of matches (i.e., run an egrep-like program on
twenty or so unique or uncommon words that appear in the message).
For you folks with high-volume lists, I know that the prospect of having
to search/egrep through each incoming post is unrealistic, but it is still
something to think about. I'm running SmartList, and my largest mailing list
is about 260 members with average of 10 messages a day (digest only).
Note that my suggestion here is based on the fact that I've received the
*same* SPAM several times (from different senders, though). This mailing
list (list-managers) could periodically post a list of patterns to filter
known SPAM -- kind of like a virus detection program update.
