These RBL lists are designed to be used by pfBlockerNG on pfSense. I normally update them once or twice a week. They are free for all uses, both personal and commercial.
SpamList is a RBL list of IP addresses that have sent my email server spam that made it through my other spam filtering.
HackerList is a RBL list of IP addresses that have attempted to hack my servers.
If your IP address is on either of these lists erroneously, you may contact me at firstname.lastname@example.org. IP addresses are not auto-pruned. The bulk of the IP addresses fall into one of two categories:
1. Machines at hosting providers who don’t care if their clients use their systems to send out spam or hack other systems. Even if the current customer gives up and stops paying to use those IP addresses, it is likely that in the future some other customer will pick them up and use them for spamming or hacking.
2. Compromised machines that are being used to send out spam or hack other systems. Even if the machine is cleaned up, most people who are compromised once will be compromised again repeatedly. So it is likely their IP address will be used for spamming and hacking again in the future.
