About vspam.org
vspam.org is a community-driven phishing intelligence clearinghouse built for mail operators, sysadmins, and security researchers. We aggregate threat reports from the global anti-abuse community and publish them as a free, queryable database and DNSBL feed.
Our mission is to make phishing infrastructure visible and actionable. Every report is community-verified. Threat data is free for non-commercial use — researchers, sysadmins, and open-source projects. Commercial use requires a license.
How it works
Report
Community members submit phishing URLs, malicious domains, spam IPs, and threat email addresses with supporting evidence.
Verify
Trusted reporters vote to confirm or reject each submission. Reports reaching the confidence threshold are marked Confirmed.
Distribute
Confirmed IOCs are published to the DNSBL feed, STIX 2.1 bundle, and REST API within seconds of verification.
By the numbers
Trust Tiers
Reporter trust is earned through consistent, accurate submissions. Higher tiers carry more weight in the confidence scoring algorithm and receive higher API rate limits.
