Threat Intelligence Log

Yes. Zero Spam checks the reputation of the IP address and email address behind each submission against a network of known abusive actors, so most spam is rejected before a human is ever asked to prove anything. Many sites remove reCAPTCHA or Turnstile entirely; others keep a challenge as a last resort for high-risk traffic only.

Incident write-ups are published as we confirm the details and are amended if the attack changes. Evergreen guides with a year in the title are reviewed at least quarterly, and the review date appears at the top of each article.

No. Every guide is free to read, and the free Explorer plan covers a small number of reputation requests a month, which is enough to check suspicious addresses by hand. Paid plans start when you want the plugin or API checking every submission automatically.

Ben Marshall, full-stack developer and engineering manager, writes and maintains the log, drawing on Zero Spam network data. Zero Spam is a service provided by Highfivery Studio and has been tracking spam reputation since 2018.
