We keep a sharp eye on the behavior of hosts around our network, to 
ensure that we don't end up with zombies here.  When we detect one, we 
deal with it quickly.  We haven't a zombie attack here in quite a 
while, and the spamcop listings have happened rather recently.

We also take other precautions to keep it from happening.

Last, we know our users aren't doing it directly because they're not 
out buying target lists for spamming (it doesn't apply to our business 
case even remotely ... and, again, we monitor the traffic behavior of 
our users; AND our announcements get channeled through a particular 
server to ensure that it doesn't impact our other email services).

There isn't anything that would point us to concluding that our users 
did it directly, nor any recent zombie activity on our network.  The 
only things that makes sense at all, and that we wouldn't be able to 
track are: user set their account's email forward to a spamtrap (which 
doesn't really make sense at all), or a spamtrap was in the return-path 
for a message that hit a vacation autoresponder.

I would applaud their stand if they did it in a manner which was 
rational and intelligent ... instead of insane and idiotic.  I have no 
problem with their "stand" (their goals).  I have a problem with their 
methods (which are often inaccurate) and their dogmas (such as their 
position on autoresponders).
