Tornevall Networks DNSBL Implementation

Tornevall Networks DNSBL and FraudBL protection for WordPress. The plugin helps block comment activity, account registrations and other unwanted submissions from addresses flagged by Tornevall Networks DNSBL and FraudBL.

FraudBL is part of the protection layer used by the plugin and is available at fraudbl.org. For general discovery, broader search terms like fraud, blacklist, comment spam and user registration are usually easier to find than niche technical acronyms alone.

The plugin is intended to provide a lightweight anti-spam and anti-abuse layer for WordPress, with support for local caching to reduce repeated lookups and unnecessary load against blacklist services.

Current admin features include manual DNS lookup tools, self-check tools, visitor statistics, safe IP whitelisting, frontend dry-run support for administrators, Cloudflare Turnstile for comments, and DNSBL plus Turnstile protection for new WordPress account registrations. WooCommerce-oriented protection is a planned next step rather than part of the current release.
