Wow -- you need to hang out here a lot longer before you make such a 
statement. Spamcop was hit by many DoS attacks in the past, because it 
does affect the spam business. Senderbase.org also gets some of its 
information (as far as I know) from Spamcop -- it's an excellent way to 
spot zombies (if only the ISPs would do something proactive with the 
information). The SURBL also gets timely information from spamcop... 
there are many other facts that prove that spamcop is having a positive 
effect.

I agree that Spamcop et al are always going to be behind the spammers -- 
  as long as there's money in spamming, there will always be a lag. Same 
goes for any kind of crime vs. law enforcement. I don't agree that all 
spammers are "way ahead" -- perhaps the most elite ones are.

It's in every legitimate business's best interest to /reject/ spam sent 
through zombies, open relays, proxies, etc., and label spam that 
contains URLs that are known spam links, etc.

REJECT is the way to go because it blocks very effectively a large 
proportion of spams and viruses. How come you can't implement a reject 
strategy?

As Miss Betsy said, spammers have "ruined" the feature of NDR and 
vacation auto-replies. You can blame spamcop if you want.

If you're still in denial about responsibility concerning the 
"backscatter" problem (getting listed because of bounced spam), you may 
want to have a look at these links, which have nothing to do directly 
with spamcop!
