What is 0spam (Fusionzero)?

0spam (also known as Fusionzero) operates community-driven blocklists focusing on spam and abuse. They maintain both IP and domain-based lists.

Impact Level: Low. Limited adoption outside of specific communities.

Zones:

• bl.0spam.org - Main blocklist
• rbl.0spam.org - RBL zone
• 0spam.fusionzero.com - Legacy zone

What triggers listing:

• Spam reports from community members
• Trap hits on 0spam's honeypot network
• Association with known spam infrastructure

Delisting: Request removal through their website after addressing the underlying issue.

0spam represents the smaller, community-driven blocklists - less reach than the giants, but still occasionally queried by mail systems.
