What is SPEWS?
Found a great essay today on how SPEWS (Spam Prevention Early Warning System) works. Thought I'd share it with you all: What is SPEWS?
News and musings about the fight against spam.

Great find! - Actually this site has great essays on what spam is and isn't. While I do not personally care for SPEWS, other such anti-spam groups are more palatable: Spamhaus, SORBS, MAPS, Spamcop, etc.
Does anyone know if SPEWS is updating their blocklistings? - last I heard from NANAE posts and whatnot SPEWS was not being updated.
There's an old saying that goes "Democracy is the worst form of government there is, except for all the others."
That's how I feel about SPEWS. I do feel they can be overly agressive, and the expanding blocks border on being punative listings, but IMHO, they are the best we've got. The fact remains that SPEWS gets the job done, and you can't argue with that. (Well, obviously you can; just read nanae.)
It's actually good to have a varied gene pool of DNSBLs; it allows administrators to choose the level of aggresiveness they want to apply to their spam problem. Ocassionally you hear of providers who even block on Spamhaus level 2 (caution) listings. At the other end of the spectrum was MAPS which was very slow to list and very fast to unlist.
Sadly, ORBS and MAPS are no longer truly players in the DNSBL game, having been sued nearly to oblivion in SLAPP lawsuits.
I hadn't heard anything about SPEWS not updating their listings, although it's possible I missed a thread in nanae. Certainly SPEWS' policy of not responding to anybody publicly or privately could create the impression they they're not updating their listings. I don't know if this has been documented one way or another, though.
