Not Just Another Bogus List (NJABL) was a

dynamic IP list is also a development from Dynablock, but is more aggressively inclusive than NJABL's version.
As of March 1, 2013, NJABL is in the process of being shut down. The DNSBL zones have been emptied. After "the Internet" has had some time to remove NJABL from server configs, the NS's will be pointed off into unallocated space (192.0.2.0/24 TEST-NET-1) to hopefully make the shutdown obvious to those who were slower to notice.
As of April 29, the above-mentioned pointing of the DNSBL NS's into 192.0.2.0/24 has been done.
As of Jan 02/2019, the domain name njabl.org was set to expire and dns servers were switched to tucows autorenew servers which would cause any lookups by servers still not having removed the configuration to have rejections.
