Register Of Known Spam Operations (ROKSO)
Professional spammers will routinely try to sign up with your network and abuse it for as long as they can. You can avoid the worst of them by checking details of suspicious customers against the ROKSO database. If they're on ROKSO, you definitely don't want them on your network.
