I hate to fill up lists about important things (like film scanning) with
off-topic issues (like spam), but I also hate to see spamcop unfairly
tarnished.
I use spamcop to filter my email, and I get very few false positives. (I
have a few friends who use aol, which comes and goes from the list).
Spamcop filters by sender IP, not sender address. I get about 700 spams/
week, of which Spamcop filters 95% or more. You are right that filtering
by email address would be pointless.
As for spamcop not delisting, I accidently listed my own ISP, and w/in 9
hours I was able to get it off the spamcop list. It wasn't easy, but it
was possible. And, in any event, all IPs listed in spamcop cycle off
after 3 days, if they are not reported again.
Spamcop has lots of problems, but I don't think that any of the issues
you list below are among them.

PS--Thanks for helping to return this list to a better level of
discussion. Sorry for the digression.
