The flaw in filtering on source IP is that you are ignoring the fact
that spam is frequently sent out via botnets of infected computers.
And that some (probably most) of those are computers that have their
IP assigned from their ISP via DHCP. Therefore that IP may belong to
an infected machine at the time that spam is sent but could come from
a legitimate, non-infected machine later on (or that machine could be
cleaned later on).

You could filter on the email address. But again it ignores the fact
that spammers will spoof the sender's email address so you end up
filtering someone else's email address that is simply being spoofed.
I don't know if in this recent case of gmail.com spam messages if you
are dealing with spoofed email addresses or actual spammer accounts
that are used/abused until they get shut down.

You could filter all @gmail users, or you could filter all postings
via Google Groups. In either case you will lose postings from myself
and no doubt a number of other legitimate contributors. Your
prerogative but rather drastic in my opinion. Next week's flavour of
the month could be @live.com, then @yahoo.com, and so on. And it
could be via regular newsgroup postings rather than Google Groups.
With a blanket filter practice that some are using you will eventually
end up seeing only your own messages (or not if your domain name
becomes the flavour of the month or if you end up with one of those
filtered IPs that was previously in use by an infected machine who's a
customer of the same ISP as you).

Content filtering and maybe subject line filtering would be more
effective/targeted. But again to each their own. I understand why
some prefer newsreaders. I prefer Google Groups (I did try a
newsreader so it's not that I didn't give it a try). I simply ignore
the obvious spam messages (and any other message where the subject
does not appear to be of interest to me). There is minimal impact on
me beyond having to scroll past them on the screen seeing I don't
download them via a newsreader.
