SpamJam starts working immediately—no configuration needed! #### After Activation SpamJam works automatically with zero configuration.

Just install, activate, and forget about spam. ### Will this slow down my site? No. SpamJam is extremely lightweight and uses efficient caching. Most users see zero performance impact. ### Will my users see captchas? Never. SpamJam is completely invisible to legitimate users. No captchas, no verification steps, no friction. ### Does this work with my theme? Yes! SpamJam works with any WordPress theme that uses standard comment forms. It’s compatible with popular themes like Astra, GeneratePress, OceanWP, and more. ### Is this compatible with WooCommerce? Yes! SpamJam is fully compatible with WooCommerce and supports High-Performance Order Storage (HPOS). ### What’s the difference between Free and Pro? The free version protects comment forms with honeypots, nonce validation, and basic blocklists. Pro adds 10+ advanced features including: – Registration form protection with email verification – Premium auto-updating blocklist (15,000+ terms) – Custom blocklist for your specific needs – Geographic and IP blocking – Rate limiting to prevent spam floods – Email whitelist for trusted users – Spam logging and analytics – Content validation rules – Contact form protection (CF7, WPForms, Gravity Forms) – Priority support ### How does geographic blocking work? Pro users can block comments from specific countries by entering country codes ( e.g., CN, RU, UA). This uses IP geolocation to identify the commenter’s country and blocks them before they can submit spam. ### What is rate limiting? Rate limiting prevents spam floods by limiting how many comments a single IP address can submit within a time period. For example, you can set it to allow maximum 5 comments per hour per IP address. ### Can I see what spam was blocked? Yes! Pro users can enable spam logging to track all blocked attempts. You can see IP addresses, countries, blocked content, and reasons for blocking. Logs are automatically cleaned up based on your retention settings. ### Does this work with other anti-spam plugins? SpamJam can work alongside other plugins, but for best results, we recommend using it as your primary anti-spam solution to avoid conflicts. ### How effective is SpamJam? SpamJam blocks 99%+ of automated spam bots. The multi-layered approach catches what single-method solutions miss. ### Do you offer support? Yes! Free users can get community support through WordPress.org forums. Pro users get priority email support. ### Is my data sent to third parties? No. SpamJam processes everything on your server. Your data stays private and GDPR- compliant. ## 评价 此插件暂无评价。 ## 贡献者及开发者 「SpamJam」是开源软件。 以下人员对此插件做出了贡献。 贡献者 * [ Matt Biscay ](https://profiles.wordpress.org/skyminds/) [帮助将「SpamJam」翻译成简体中文。](https://translate.wordpress.org/projects/wp-plugins/spamjam) ### 对开发感兴趣吗? 您可以[浏览代码](https://plugins.trac.wordpress.org/browser/spamjam/)，查看[SVN仓库](https://plugins.svn.wordpress.org/spamjam/)， 或通过[RSS](https://plugins.trac.wordpress.org/log/spamjam/?limit=100&mode=stop_on_copy&format=rss) 订阅[开发日志](https://plugins.trac.wordpress.org/log/spamjam/)。 ## 更新日志 #### 2.2.2 – 2026-05-29 * Fixed – Wrapped all plugin functions inside the Freemius function_exists guard to prevent “Cannot redeclare” fatals when free and premium builds load together during an upgrade switch (F1) * Fixed – Comment form action now sets the sj5 token on DOMContentLoaded instead of on scroll, so legitimate commenters who never scroll are no longer blocked with “Form validation failed” (F2) * Security – sj5 HMAC token is now time-boxed and rotates hourly (accepts current and previous window) to prevent indefinite token replay; validated with hash_equals()( S1) * Fixed – Empty/missing HTTP referer is no longer hard-blocked, eliminating false positives for privacy browsers, Referrer-Policy: no-referrer, and proxies (S2) * Enhancement – WooCommerce: comment protection script no longer loads on product pages for users who cannot leave a verified-purchase review ## 额外信息 * 版本 **2.2.2** * 最后更新：**16 小时前** * 活跃安装数量 **100+** * WordPress 版本 ** 6.2 或更高版本 ** * 已测试的最高版本为 **7.0** * PHP 版本 ** 7.4 或更高版本 ** * 语言 * [English (US)](https://wordpress.org/plugins/spamjam/) * 标签 * [comment spam](https://cn.wordpress.org/plugins/tags/comment-spam/)[honeypot](https://cn.wordpress.org/plugins/tags/honeypot/) [security](https://cn.wordpress.org/plugins/tags/security/)[spam protection](https://cn.wordpress.org/plugins/tags/spam-protection/) * [高级视图](https://cn.wordpress.org/plugins/spamjam/advanced/) ## 评级 尚未提交反馈。 [Your review](https://wordpress.org/support/plugin/spamjam/reviews/#new-post) [查看全部评论](https://wordpress.org/support/plugin/spamjam/reviews/) ## 贡献者 * [ Matt Biscay ](https://profiles.wordpress.org/skyminds/) ## 支持 有话要说吗？是否需要帮助？ [查看支持论坛](https://wordpress.org/support/plugin/spamjam/) ## 捐助 您愿意支持这个插件的发展吗?
