How to report spam to blacklists

Solution 1:

No, there is no central spam blacklist service that I'm aware of. However, you could gather a comprehensive list of blacklists and then search each of them for user submission forms here's a small sampling:

• http://www.ahbl.org/
• http://www.backscatterer.org
• http://barracudacentral.org/rbl
• http://dnsbl.burnt-tech.com/
• http://cbl.abuseat.org/
• https://www.dan.me.uk/dnsbl
• http://www.dnsbl.info/

...to name a few. Check out a few lists of black lists to get a much larger bunch. For example:

• http://www.moensted.dk/spam/
• http://ipindex.homelinux.net/index.php?action=check_on_dnsbl

Solution 2:

Most blacklists use multiple methods to determine spammers. It would really suck if all it took was 1 complaint to put you on a blacklist. So they use honeypot email addresses and all sorts of heuristics to determine if somebody is spamming. They can function pretty well without submissions. But nothing is perfect. That's why it's good to rely on multiple methods for determining spam.
