ActiveLayer Anti-Spam: Spam Protection for Forms & Comments

Anti-Spam Protection Without CAPTCHAs

ActiveLayer is an intelligent anti-spam solution that stops contact form spam, comment spam, and registration spam without CAPTCHAs, puzzles, or extra steps for your visitors. Your forms stay fast and frictionless while unwanted messages get caught automatically.

Your time and attention are expensive — stop spending them on spam. ActiveLayer protects popular form builders like WPForms, Contact Form 7, Gravity Forms, Elementor Forms, Fluent Forms, and WS Form, plus native WordPress comments, WooCommerce (product reviews and customer registration), AffiliateWP, MemberPress, and BuddyPress / BuddyBoss signup forms, all from a single plugin. With 16 integrations, you manage all your spam protection from one settings page.

Zero Friction Spam Filtering

Most anti-spam tools either show visitors a CAPTCHA or make every form wait while the check runs. ActiveLayer takes a different approach. Async integrations complete immediately while background checks run through Action Scheduler; registration and inline-blocking integrations can run a synchronous check when spam must be stopped before an account, entry, or affiliate record is created.

This keeps normal form workflows fast while still allowing high-risk signup flows to block spam inline. If a submission is clean, notifications are sent as normal. If it is flagged, notifications are suppressed or the signup is blocked depending on the integration.

Intelligent Spam Detection

ActiveLayer analyzes submission patterns, content reputation, behavioral signals, and environment data to catch both automated bots and human bad actors with high accuracy. Unlike simple honeypot or keyword-blocklist approaches, ActiveLayer uses multiple signals to make smarter decisions about every submission.

Optional behavioral tracking monitors how users interact with your forms — keystrokes, mouse movements, touch events, and scroll patterns. Environment detection identifies headless browsers and automated tools. These client-side signals are sent alongside form data for deeper analysis.

Per-Form Control and Sync Mode

You decide exactly which forms to protect. ActiveLayer protects all supported forms and WooCommerce surfaces by default after your API key is connected — you can disable protection per form if needed. This gives you granular control over every contact form, registration form, or comment section on your site.

Sync Mode lets supported integrations wait for the API verdict before the submission completes, so spam can be blocked inline. By default, ActiveLayer runs checks asynchronously for maximum speed. Turn Sync Mode on when you prefer inline blocking and can tolerate a small added latency on submissions.

Fail-Safe by Design

If the ActiveLayer API is temporarily unavailable, your forms keep working. ActiveLayer is designed to fail open — it restores provider defaults, preserves every submission, and retries background checks automatically when connectivity returns. No lost submissions, no blocked emails, no broken forms.

Automatic retries handle transient failures. A built-in watchdog checks queue health every 15 minutes and shows admin notices when pending items build up or Action Scheduler is unavailable. You always know the status of your protection.

Full Visibility Dashboard

See exactly what is happening with your form protection at a glance. The ActiveLayer dashboard shows submission totals, spam caught, accuracy rates, queue health, and integration status — all in one place. Filter submissions by status or provider, and use bulk actions to recheck, mark as clean or junk, or trash items you no longer need.

Every submission is logged in a custom database table. You can review verdicts, recheck past submissions with a fresh API call, and override any decision. Debug logging (opt-in, PII-redacted) gives you even deeper insight when troubleshooting.

Who Is ActiveLayer For?

Small Business Websites

Protect your contact forms and inquiry forms without adding friction for potential customers. Async form submissions from real visitors go through instantly while junk gets caught behind the scenes.

Bloggers and Publishers

Stop comment spam on your posts without requiring readers to solve CAPTCHAs or prove they are human. ActiveLayer checks comments in the background and can auto-approve clean ones or auto-mark detected spam.

Agencies Managing Multiple Sites

One plugin covers WPForms, Contact Form 7, Gravity Forms, Elementor Forms, Fluent Forms, Formidable Forms, WooCommerce, and more — every integration managed from one settings page. No need to configure separate anti-spam tools for each form builder or WooCommerce surface your clients use.

E-commerce and Service Businesses

Keep inquiry and support forms clean while maintaining a fast, professional user experience. Async checks keep contact forms moving quickly, while registration gates can block spam accounts inline. WooCommerce stores get dedicated protection for product reviews and My Account customer registration — and the checkout itself is never gated, so spam protection can’t get in the way of a sale.

Membership Sites and Online Communities

Running a community on BuddyPress or BuddyBoss Platform? ActiveLayer hooks the public signup form and blocks spam registrations before they create fake accounts — no extra CAPTCHA in front of your real members, no manual moderation queue to babysit. The integration covers both free BuddyPress and BuddyBoss Platform with a dedicated admin toggle for each.

External services

This plugin connects to the ActiveLayer API to analyze form submissions and comments for spam. It is the core service that powers all spam detection — without it, the plugin cannot classify submissions.

ActiveLayer API

What it does: Provides spam detection verdicts (clean or spam) for form submissions and comments.

When data is sent: Each time a protected form submission, comment, review, or registration is checked, the submission data is sent to the API for analysis. Depending on the integration, this can happen through the background queue or during a synchronous inline-blocking check.

What data is sent:
* Submission content (name, email, message, URL if provided)
* IP address and user agent of the submitter
* Form metadata (form ID, form name, provider name)
* Site URL and WordPress locale
* Behavioral and environment signals (if enabled in settings)

Service provider: ActiveLayer (activelayer.com)
* Terms of Service
* Privacy Policy

1.4.1

• Improved: WooCommerce — account registration during checkout now completes smoothly without an inline spam check, keeping the purchase flow uninterrupted. The standalone My Account registration form stays protected.
• Improved: MemberPress — paid memberships complete signup without an inline spam check for a seamless checkout. Free memberships, free trials, and fully-discounted signups remain protected, with an optional setting to extend checks to paid signups.

1.4.0

• Added: AffiliateWP integration — synchronous protection for affiliate registration before the affiliate and WordPress user are created.
• Added: MemberPress integration — synchronous protection for membership registration before the WordPress user account and membership are created.
• Added: WS Form integration — synchronous spam blocking before WS Form saves entries or runs actions, with per-form protection controls.
• Added: New translations — Italian, Japanese, Dutch, Brazilian Portuguese, and Simplified Chinese.
• Fixed: Message body — links and line breaks in submitted messages are now preserved when sent to the spam API, improving detection accuracy.
• Fixed: WPForms — marking an entry as “Not Spam” in the admin no longer re-runs detection or reverts the entry.
• Fixed: Dashboard — the plugin recommendation now detects and activates an already-installed Pro variant instead of downloading the Lite version.

1.3.1

• Fixed: Internal plugin version constant was left at 1.2.0 in the 1.3.0 release, so browsers and page caches kept serving outdated CSS/JS assets after the update. Asset cache-busting now works correctly again.

1.3.0

• Changed: Form protection now enabled by default for all supported providers after API key connection. Existing forms with explicit disable setting remain disabled until re-saved.
• Added: BuddyPress and BuddyBoss integration — anti-spam protection for community signup (registration) forms. Blocked signups are labelled “Member” in the Submissions log.
• Added: One-click Connect — create and link your free account in one step, with the API key saved automatically on return.
• Fixed: PHP 8.4 compatibility — explicitly typed nullable constructor parameters to silence the new implicitly-nullable deprecation notice (behaviour unchanged on PHP 7.2+).

1.2.0

• Added: WooCommerce integration umbrella — full anti-spam coverage for the two highest-risk WooCommerce surfaces (Product Reviews and Customer Registration), managed from a single panel under ActiveLayer → Integrations.
• Added: WooCommerce Reviews protection — every product review is scored on submission, with optional verified-owner bypass, logged-in-user bypass, and high-confidence auto-delete.
• Added: WooCommerce Registration protection — blocks bot signups on the My Account form, classic [woocommerce_checkout], and the new Cart/Checkout Blocks (default since WooCommerce 8.3). The “Allow customers to create an account during checkout” setting is honoured in every flow.
• Added: Silent-discard option for high-confidence spam comments and WooCommerce reviews — items at or above the configurable score threshold (default 95) are hard-deleted instead of moved to the spam folder. (#127)
• Added: Native moderation feedback for WordPress comments and WooCommerce product reviews — moderator decisions (approve / spam / trash) are sent back to the ActiveLayer API to improve detection accuracy.
• Fixed: Comments — moderator email notifications are now suppressed until ActiveLayer returns a verdict; deferred notification is dispatched correctly when a held comment is restored.
• Fixed: WooCommerce Reviews — moderator notifications are likewise suppressed while a review awaits classification.
• Fixed: Fluent Forms — abort message is now sent as a string to prevent a frontend TypeError when a blocking message is shown.
• Fixed: Submissions — the View Submission screen now surfaces the API error message for failed submissions instead of hiding the API Response panel entirely, making API outages easier to diagnose.
• Fixed: WPForms Pro — duplicate notification emails on failed-submission retries. EmailReconstructor::allow_submission() is now idempotent: a persistent marker on the WPForms entry prevents the daily retry sweep from re-releasing already-sent notifications when the API is unavailable. (#154)
• Fixed: Gravity Forms — admin notifications arrived with an empty body and stripped subject merge tags when ActiveLayer protection was enabled.
• Compatibility: Tested up to WordPress 7.0.
