It's not up to Spamcop to "do" anything- they simply make it easy for you to report it to all the ISPs involved. Some of them don't give a shit, but many do.. I have had a few of my "regular" spammers drop out after I reported them.. I also make sure to see if I can recognize the sponsor and do a specific report there as well, that seems to help.
Cheers,
