Frequently Asked Questions

Common questions about SpamJam – Anti-Spam Protection for Comments & Forms

Yes. Core comment protection is enabled by default with sensible settings. You can fine-tune it from the SpamJam admin screen, but you do not need to configure an API key or build rules before getting protection.

SpamJam is designed to stay focused and load its comment-protection script only on pages where comments are open. It has no jQuery dependency, and premium feature files load conditionally when their features are enabled.

No. SpamJam's core protection uses hidden traps, secure tokens, timing, and request signals instead of CAPTCHA challenges.

SpamJam works with standard WordPress comment forms and includes a fallback selector for themes that use a custom form ID. A developer filter is available for unusual comment-form markup.

Yes. The free version protects WooCommerce product review forms and declares compatibility with High-Performance Order Storage (HPOS). SpamJam Pro can also protect WooCommerce account registration.

Free focuses on automatic comment and product-review protection. SpamJam Pro adds registration and third-party form coverage, custom rules, an actionable spam inbox, targeted blocking, deeper analytics, reporting, multisite synchronization, and white labeling. Every Pro license includes the complete feature set; licenses differ only by the number of sites covered.

SpamJam Pro can block comments from selected country codes. When enabled, SpamJam uses an external IP geolocation lookup and caches the result to reduce repeat requests.

Rate limiting caps how many comment submissions one IP address can make during a configurable period. It helps contain bursts without changing the experience for ordinary commenters.

SpamJam Pro adds a searchable inbox for blocked events, reasons, sources, and review status. You can configure retention and choose whether to keep the minimum recovery data needed to restore a false-positive comment.

It may, but running multiple plugins that modify or validate the same comment form can create duplicate checks or conflicts. Test the combination on a staging site and avoid overlapping protection where possible.
