About vspam.org
vspam.org is an operator-grade phishing and abuse reputation platform built for mail operators, sysadmins, and security researchers. We combine deterministic enrichment, historical evidence, reporter reputation, and community review to publish domain, IPv6, IPv4, ASN, and email intelligence.
Our mission is to make phishing infrastructure visible and actionable without turning community voting into the sole source of truth. Threat data remains free for non-commercial use by researchers, sysadmins, and open-source projects. Commercial use requires a license.
How it works
Normalize
URL submissions are collapsed to canonical domains at ingest, while exact IPv4 and IPv6 host reports keep infrastructure precision.
Enrich & Score
DNS, WHOIS, hosting, brand, redirect, ASN, and history signals feed a deterministic scoring model with explicit confidence and reasons.
Review & Delist
Reporter trust, community voting, and delist workflows help catch novel abuse while reducing false positives and bad listings.
Publish
High-confidence domains and exact hosts are published for blocking, while IPv6 prefix and ASN outputs are exposed as watch or reputation feeds.
Platform overview
Trust Tiers
Reporter trust is earned through consistent, accurate submissions. Higher tiers carry more weight in review workflows and receive higher API rate limits, but feeds and blocking recommendations are not based on votes alone.

|---|---|---|---|
| New | 1× | Account created | Submit reports, cast votes |
| Contributor | 2× | 50+ confirmed reports | API access, CSV export |
| Verified | 4× | Org email + 200+ reports | STIX export, bulk submit |
| Trusted | 8× | Invite-only, vetted operators | Unlimited API, DNSBL zone access |
