The SpamCop BL is a fair representation of the sending IPs of the messages that its users are reporting as spam. One of your goals as an ESP should be to not get perceived as spam in the mailboxes of those users. If the users get your messages and report them as spam (via SpamCop, AOL, etc.), then you may be doing something inappropriate that's worth reviewing and correcting.
In a lot of cases, that seems to boil down to "sending a legitimate email to a recipient who once *asked* to be sent such email, who has now forgotten they signed up in the first place". :(
There's not much a sender can do about that - particularly for periodic emails of the type *many* companies send to customers (or potential customers) who have signed up for these messages.
