ActiveLayer Anti-Spam vs La Sentinelle antispam

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, WS Form, and FunnelKit Funnel Builder, plus native WordPress comments, WooCommerce (product reviews and customer registration), Easy Digital Downloads (store reviews and customer registration), AffiliateWP, MemberPress, and BuddyPress / BuddyBoss signup forms, all from a single plugin. With 18 integrations, you manage all your spam protection from one settings page. Create a free account and get started 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.

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

I will make a request on make/polyglots to have you added as validator for this plugin/locale. How to choose an antispam plugin When you look through the WordPress Plugin Repository you will see more than a hundred antispam plugins. Which one is the best one? Short answer, there is no “best one”. No spamfilter and no method for spamfiltering is perfect. Slightly longer answer, you could try about twenty and choose the one that fits your needs best. But there is also a really long answer. There are different methods that can be used against spam, and every method has its drawbacks. In my opinion, having a low number of false positives is more important than perfectly marking all spam, you don’t want to miss out on important people or information. Nagging the user in some way has a similar effect, the user might not even want to bother with that and just walk away. Third party services: Services like Akismet, OOPSpam, Stop Forum Spam and also reCAPTCHA offer third party services to check for spam. This can be very effective, but you are giving user submitted data away to these third parties and are also giving your users up for tracking them. Captcha’s, reCAPTCHA and Quizz Questions: You are annoying your users and probably sending some of them away. This especially counts for reCAPTCHA for visitors who have third party cookies disabled. Blacklists: Often running behind the facts. That goes for the way of getting users off that list, and also in getting users on that list. Referer check: check if the Referer header is set correctly. You can never trust it is set correctly. Modern browsers are limiting the use of Referers, though for now that is mostly for third-party domains. JavaScript methods: Spammers often (always?) don’t use JavaScript, they just post the form with spammy data. Drawback for this method is that statistics say that about 1 percent of users has JavaScript disabled. Also, some websites have broken JavaScript, which might make the spamfilter break as well. Activation email for registering users. Users only get activated after clicking a link in an activation email. You still have all the non-activated users in your site however. You could have a bright idea about combining several methods, but then you get the drawbacks of all the methods you use. Another complication of choosing a good plugin is that most antispam plugins don’t tell you what methods they use. The documentation doesn’t tell you, and looking at the source code just leaves you confused at the chaos that it often is. My main motivation for writing this plugin is to offer a plugin that does spamfiltering with JavaScript methods in a simple and effective way. The claimed 1 percent of users that has JavaScript disabled will also be tech-savy enough to enable it again for your website. Compatibility This plugin is compatible with ClassicPress.
