Do you really mean Spam
cop ? Spamcop.net is a database of IPs of "known" spammers, against which the sender can be checked. Just about every ISP (yes, a whole ISP, e.g. Yahoo) has ended up on Spamcop at one time or another. Obviously they moan like hell and SC then removes them, if it doesn't do it automatically after a few hours.
Spamcop is responsible for a lot of missing emails.
Out of the ~ 4000 spams a day I get at work, spamcop removes about 3000. The remainder is still too much to check manually, or to process with Mailwasher (which also requires a manual check).
Spamcop is also a part of the problem. They are blacklisting ISPs that implement a challenge mechanism - the only really good way to handle large amounts of spam.

It means your email address has not got "out" yet. Just wait until a few of your non-computer-literate friends get infected with address book harvesting trojans. Then you will have loads of friends
