DGN Webs Spam User Cleaner scans your WordPress users and identifies likely spam registrations using a multi-signal scoring engine — no external API required for the core features.

Every email address is scored across multiple heuristic signals. Users scoring above your chosen minimum threshold appear in a reviewable list. You decide who to delete — nothing is removed without your confirmation.

Privacy & External Connections

This plugin performs no external connections. MX record validation uses PHP’s built-in checkdnsrr function — a standard DNS query. No user data is sent to any third party.
