Spamcop runs on full auto and has been for years. They take pretty much anyone's word about whether a site is spamming, and last time I looked around their site, they don't seem much bothered by the fact that they kill a lot of legitimate e-mail that way.

They auto-age entries out of their database in a day or two of no spam reports, and they seem to believe that this is sufficiently quick for bad entries to go away.

I have no use nor respect for the spamcop system - they don't give a rat's that they are trivially used as a DOS attack, and they don't care that you a lot of e-mail goes missing because of them.

Any anti-spam solution that regularly drops real mail on the floor is NOT a solution - it's a problem of it's very own.
