Spamcop is out of control with their "Guilty until proven innocent" attitude. One of the main problems is that even if you run a 100% clean mailing list, there's always going to be one bozo who doesn't know how to subscribe and thinks that complaining to Spamcop works, so why not use that method?
That's how I ran into trouble with them. Yes, I was able to prove that the person was properly subscribed, but (1) I shouldn't have to "show my papers" because some idiot didn't know what she was doing, and (2) even though I was found innocent, email of mine was blocked for a week. Spamcop is very simply an extremely easy way to run a denial of service attack on anyone, from an enemy to a competitor. And therefore, it's a lawsuit waiting to happen.
