FAQ

Does this plugin require any external services?

No, HighPots Spam Protection works entirely within your WordPress installation. No external API calls or third-party services are required. This means no monthly fees, no API limits, and better privacy.

Will this plugin slow down my website?

No, the plugin is designed to be lightweight and efficient. It uses optimized database queries and smart caching to minimize performance impact. Most sites won’t notice any speed difference.

Is this plugin GDPR compliant?

Yes, the plugin masks IP addresses for privacy (e.g., 192.168.xxx.xxx) and doesn’t store any personal data unnecessarily. All logging is designed with privacy in mind and can be configured or disabled entirely. Data retention periods are fully configurable.

Can I customize the spam detection rules?

Yes, you can configure timing thresholds, rate limiting parameters, and blocked writing systems through the admin interface. The plugin provides fine-grained control over all protection mechanisms.

Can I enable/disable protection for specific form plugins?

Yes, each form plugin integration can be independently enabled or disabled in the settings page. This allows you to protect only the forms you want while leaving others unprotected if needed.

Does this work with custom forms?

Yes, the plugin automatically protects any HTML forms on your site. For custom integrations, developers can use the provided classes and hooks.

What happens to legitimate users if they’re flagged as spam?

The plugin is designed to minimize false positives. If a submission is blocked, users will see a clear error message and can try submitting again after a short delay. You can adjust the timing and rate limiting settings to reduce false positives further.

Can I export spam logs?

Yes, the plugin includes a CSV export feature for analyzing spam patterns and compliance reporting. You can export logs for any date range in either detailed or summary format.

How does the multilingual support work?

The plugin automatically detects your WordPress language setting and displays the interface in the appropriate language. No additional configuration is needed. If your language isn’t supported yet, the plugin falls back to English.

Is this compatible with caching plugins?

Yes, the plugin is designed to work with popular caching plugins like WP Super Cache, W3 Total Cache, and WP Rocket. It uses WordPress transients for efficient caching and doesn’t interfere with page caching.

Can I disable specific protection features?

Yes, each protection method can be individually configured or disabled through the settings page, allowing you to customize the protection level for your specific needs.

Does this work with reCAPTCHA or similar tools?

Yes, you can use HighPots Spam Protection alongside other anti-spam tools. However, many users find they don’t need additional tools once HighPots is configured properly.

Will this block legitimate submissions from international users?

The writing system blocking is optional and can be customized. By default, all writing systems are allowed. You only need to block specific character sets if you’re experiencing spam in those languages and don’t expect legitimate submissions using them.
