Do everyone a favour, go after the spammer *and* SpamCop. I'm sick of playing games with email because some anti-spam fascist dictates how we are allowed to use email.
Fining for speeding and jaywalking. That's bad! I mean you were in a hurry and no-one was in danger. I don't need to respect that stop sign, it's stupid! Damn fascist police dictating how to behave in the society!
Lets have a world without rules, just anarchy...
...or maybe not.
Smapcop does NOT block anything unless if someone
volunteerily uses the service (individual or ISP). Spamcop is not blocking anything, the receiver is. So you blame the wrong party from the beginning...
Even if spamcop occasionally block some large servers, it still pays off in the end. The ratio of crap blocked per problems caused is fair enough. Also, if some large ISP gets into spamcop blacklist, it IMO is just a wakeup call for the adminstrators to do better job. Usually when this happens they check and fix all mailservers in their control, to make sure this embarrassement doesn't happen ever again.
