A comprehensive step-by-step guide to protecting WordPress sites from spam across comments, contact forms, and user registrations. Covers free built-in WordPress settings (comment moderation, trackback disabling, link limits), AI-powered server-side spam filtering tools (ActiveLayer, Akismet, CleanTalk), CAPTCHA options (Cloudflare Turnstile vs Google reCAPTCHA), honeypot techniques, time-based behavioral checks, country/IP/email blocking in WPForms, email confirmation for user registrations, DNS-level firewall setup with Cloudflare, and bulk cleanup of existing spam comments and fake accounts. Recommends a layered defense strategy rather than relying on any single tool.
