Combination of BABL (Bad Abuse Backlist), CABL (Chronic Abuse Blacklist), and STABL (Short Time Abuse Blacklist) blacklists.
BABL (Bad Abuse Backlist) has three parts:
1. The first set contains IP ranges that reportedly do not want to receive abuse notices to their officially registered abuse address. Companies that refuse to publish an abuse address and refuse notices to alternative e-mails.
2. The second set contains ranges belonging to registered abuse addresses that have been undeliverable for at least 3 of the last 7 days.
3. All IP space without an abuse e-mail listed on the IP registry information.
CABL (Chronic Abuse Blacklist) blacklist contains ranges belonging to registered abuse departments that have issues reported but the issues have not been resolved within last 30 days. In an effort to help some departments under high load to resolve each issues, they are tracked separately so new attacks are not lumped in with the old ones.
STABL (Short Time Abuse Blacklist) blacklist contains only the IPs where abuse has occurred at least twice within the last 48 hours. Automatic removal is done 24 hours after abuse has stopped.
