How to report spam to blacklists

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.

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

You could always report them to their ISP. Take a look at the whois (or tracert) results, and see who is providing them with bandwidth/transit. Reporting to them would probably get a better response then reporting to some random blacklist.
