Comparison

Scam Lookup vs URLVoid

URLVoid is a blocklist aggregator — it queries roughly 30 threat-intelligence services and tells you whether any of them have flagged a domain. That's useful, but it only catches the fraction of scam sites that have already made it onto a public blocklist (usually days or weeks after the first victims). Scam Lookup analyzes the site itself — DNS, SSL, headers, domain age, email security, transparency signals — and returns a verdict based on trust signals a scam site almost never satisfies. Both approaches are complementary.
