SpamCop simply notes what addresses appear to be emitting spam. If your network is emitting spam and SpamCop users or traps detect it, then yes your IPs can get blacklisted. The best way to solve that is to stop the emission of spam from your network.
As was already suggested, one good way to do that is to block direct port 25 output from your network and instead direct users to officially sanctioned outbound smtp servers. This has become a standard practice for many ISPs, wireless networks, companies, hotels, wifi hotspots, etc., these days for the good reason that it defeats most outbound spam from viruses/bots/zombies. While SpamCop's trap addresses don't provide visible analyses of headers IIRC, user reports do, so that you can see how the headers were interpreted. Usually they are interpreted correctly these days. There is a link in the reports that shows the analyses. You can also sign up for an account that gives periodic reports for your networks. As has already been noted, this is not an appropriate place to b!tch about SpamCop.
