SolverGuard Spam Shield is the only free WordPress plugin that protects every entry point of your site — contact forms, comment sections, user registrations, login page, REST API, XML-RPC, and your server itself — with zero shortcodes and zero per-form configuration required. While most anti-spam plugins protect only one area of your site, SolverGuard deploys 30+ independent protection layers across six major modules. Install it, activate it, and your entire WordPress site is defended immediately. “Set it and forget it” protection — works automatically from the moment you activate.” 🛡️ MODULE 1: Contact Form 7 Protection Six independent spam-fighting layers apply automatically to every CF7 form on your site — no per-form setup needed. 🍯 Honeypot — An invisible hidden field is silently injected into every form. Real users never see it or fill it in. Bots that auto-fill every field get caught instantly and blocked. ⏱ Time-Based Check — Bots submit forms in milliseconds; humans take a few seconds to read and fill out a form. This module blocks submissions that arrive suspiciously fast (bots) or from stale, expired sessions, eliminating both automated attacks and session replay attacks. 🚫 IP Blocker — Block individual IP addresses or entire CIDR network ranges (e.g. 10.0.0.0/8) from submitting any form on your site. The same block list is automatically shared with comments, login, and registration protection for maximum coverage. 🔤 Keyword Filter — Case-insensitive keyword and phrase matching scans every submitted form field simultaneously. Block spam phrases, competitor names, casino/pharma keywords, or any custom list of prohibited terms. 📈 Rate Limiter — Caps the number of form submissions per IP address within a configurable sliding time window. Stops bots that submit the same form hundreds of times per hour, without ever impacting real users. 🤖 Google reCAPTCHA v3 — Silent, frictionless bot scoring via Google’s reCAPTCHA v3. No annoying checkboxes or image puzzles for real visitors — the score is calculated invisibly in the background and submissions below your threshold are blocked automatically. 💬 MODULE 2: Comment Spam Protection Ten layers of dedicated comment spam protection, covering every submission path including Gutenberg and headless REST API setups. 🍯 Comment Honeypot — A hidden anti-spam field is injected into every WordPress comment form automatically. ⏱ Comment Time Check — Blocks comments submitted too quickly after page load (bots) or from sessions that expired too long ago. 🚫 IP Blocking — Automatically reuses the shared IP block list — block an IP once, block it everywhere. 📈 Comment Rate Limiter — Separate per-IP rate limiting specifically for comments, independent of form rate limiting. 🔤 Comment Keywords — A global keyword list plus comment-specific blocked phrases. Stop spam before it reaches your moderation queue. 🔗 Link Count Limit — Block comments containing more than a configurable number of hyperlinks — the #1 hallmark of spam comments. 📧 Email Domain Blocking — Block registrations and comments from disposable or known spam email domains. Enter a list of blocked domains and all matching email addresses are automatically rejected. 🤖 User-Agent Filtering — Block comments from known spam bot user-agents. Optionally block requests with no user-agent header at all. ⏳ Hold Comments With Author URL — Automatically sends comments from authors with a URL in their display name to moderation, rather than publishing them instantly. 🌐 REST API Protection — All comment spam checks also apply to submissions made via the WordPress REST API (used by Gutenberg and headless/decoupled WordPress setups). 🔐 MODULE 3: Login & Brute-Force Protection Stop hackers from guessing your password with automated brute-force attacks. 🔒 Login Rate Limiting — After a configurable number of failed login attempts from the same IP, further attempts are blocked for a configurable lockout period. Stops dictionary attacks and credential-stuffing bots cold. ⏱ Configurable Lockout — Set exactly how many failed attempts trigger a lockout, and how many minutes the lockout lasts. Default: 5 attempts, 15-minute lockout. 📋 Full Audit Logging — Every blocked login attempt is logged with the IP address, timestamp, and the reason for the block, so you can see exactly what threats your site faces. 👤 MODULE 4: Registration Spam Protection Block fake accounts and spam bot registrations before they are ever created in your database. 🍯 Registration Honeypot — A hidden field traps bots that auto-fill every registration field. ⏱ Registration Time Check — Blocks registrations submitted impossibly fast or from expired form sessions. 📧 Email Domain Blocking — Block registrations from specific disposable email domains. Subdomain matching included — blocking spammail.com also blocks [email protected]. 🔤 Username & Email Keyword Filter — Blocks registrations with prohibited words in the username or email address. 📈 Registration Rate Limiter — Limits the number of registration attempts per IP in a configurable period. 🌐 REST API & XML-RPC Coverage — Protection applies to ALL registration paths: the standard form, the WordPress REST API, and direct wp_insert_user() calls. Fake accounts are blocked before they are ever written to the database, which also prevents WordPress from sending notification emails for blocked registrations. 🤖 MODULE 5: Advanced Bot Protection A dedicated bot-detection engine that runs before WordPress even fully loads — blocking malicious traffic at the earliest possible moment. 🕵️ Known Bad Bot Blacklist — 30+ built-in user-agent signatures covering scrapers (AhrefsBot, SemrushBot, MJ12bot), vulnerability scanners (Nikto, sqlmap, WPScan, Acunetix, Nessus), DDoS tools (Slowloris, LOIC), AI crawlers, and spam bots. Fully customizable with your own additional signatures. 🚫 Empty User-Agent Blocking — Blocks all requests with no User-Agent header — a near-universal sign of automated attack traffic. 🔍 Fake Googlebot / Bingbot Detection — Real Googlebots come from specific Google-owned IP ranges with verifiable reverse DNS. This module performs a live reverse DNS lookup to verify any request claiming to be Googlebot or Bingbot, and blocks fakes that don’t pass verification. Protects your server resources from being wasted on impersonators. ⚠️ Suspicious URL Pattern Blocking — Blocks probes for sensitive files and attack patterns including: /wp-config.php, /.env, /.git/, /.htaccess access attempts Web shell uploads (shell.php, c99.php, r57.php) Directory traversal attacks (../../) SQL injection in URLs (UNION SELECT, DROP TABLE) XML/XXE injection attempts phpMyAdmin and database tool probes WordPress scanner paths (/wp-content/uploads/*.php) 🌊 Request Flood Protection — Sitewide per-IP rate limiting that blocks any IP sending excessive requests within a configurable time window. Stops DDoS and scraping attacks that would otherwise overload your server. 🔒 HTTP Method Filter — Blocks unnecessary and dangerous HTTP methods such as TRACE and CONNECT that are used by certain attack tools. 🛡️ Security Headers — Automatically adds five HTTP security headers to every response: X-Content-Type-Options: nosniff X-Frame-Options: SAMEORIGIN X-XSS-Protection: 1; mode=block Referrer-Policy: strict-origin-when-cross-origin Permissions-Policy: geolocation=(), microphone=(), camera=() 🎭 Hide WordPress Version — Removes the WordPress version number from page source, RSS feeds, script/style URLs, and HTTP headers — making version-specific exploit scanning much harder. 👤 Block Author Enumeration — Blocks the ?author=1 URL trick that attackers use to discover your WordPress usernames before launching targeted brute-force attacks. ✏️ Custom Bot Signatures & URL Patterns — Add your own custom bot user-agent signatures and URL regex patterns directly from the admin panel. ⚙️ MODULE 6: General WordPress-Wide Protection Site-wide hardening that protects your WordPress installation at the infrastructure level. 📡 XML-RPC Protection — Fully disable XML-RPC (a common DDoS amplification vector), or choose the surgical option: disable only the pingback methods while leaving the rest of XML-RPC available for legitimate use (e.g. mobile apps). 🔗 REST API Rate Limiting — Rate-limit unauthenticated REST API requests per IP to prevent API abuse by bots and scrapers. 🚫 REST API User Enumeration Block — Automatically blocks unauthenticated access to the /wp/v2/users REST endpoint, which attackers use to harvest all WordPress usernames on your site. 🏓 Trackback & Pingback Spam Blocking — Block all incoming trackback and pingback requests sitewide. Also removes the X-Pingback HTTP header and the pingback URL from your blog info to hide the endpoint from probes. 🔗 Comment Author URL Hold — Automatically sends any comment to moderation when the author’s display name contains a URL — a common spam technique. 📊 Spam Log & Reporting Full Audit Log — Every blocked request is logged with the IP address, user-agent, submission data, block reason, and timestamp. Available under Anti-Spam Protection → Spam Log. Filter by Module — Quickly find blocked entries by protection module (honeypot, rate limiter, bot protection, login, registration, etc.). Automatic Log Cleanup — Set a log retention period in days and old entries are automatically purged. Keep your database clean without manual work. One-Click Log Clear — Clear all log entries instantly from the admin panel. ✅ Why Choose SolverGuard Spam Shield?
