Spamhaus makes the DROP data available (which I believe is also
included in their SBL), which is useful for using firewalls to just
block or ignore connections from the worst offenders:
DROP Advisory Null List :: The Spamhaus Don't Route Or Peer
Lists
https://www.spamhaus.org/drop/
UCE Protect also has level 3 listings for the worst offenders,
although I don't recall the list being downloadable for firewall use:
UCEPROTECT Blacklist Policy LEVEL 3
https://www.uceprotect.net/en/index.php?m=3&s=5
The problem with all DNSBL providers including the same data from
one source is that errors can unfairly penalize with major impact
that DNSBL operators generally try to prevent.

The entire open source software movement is probably one of the very
best examples of altruistic sharing. Supporting people who create
useful open source solutions and/or contribute to open source deserve
financial support so they can more easily pay their bills too. :)
