What it does
Pre-moderation quietly kills your site's conversations - comments sit in a queue, users wait for approval, and your team burns time moderating. The Real Person Badge fixes that. CleanTalk verifies every commenter in the background and publishes real people instantly - so conversations happen in real time. Verified authors earn a green "Real Person" badge next to their name. Bots are filtered out silently.
Website security platform with anti-spam, and uptime monitoring. Plugins, API, and online blocklists supported.
Top-rated anti-spam protection for websites and eCommerce. No CAPTCHA, no puzzles, no visitor friction. Explore Anti-Spam plugins and features. CleanTalk vs reCAPTCHA , vs Akismet . Unlimited REST API requests for checking POST data and user-generated content across your website and apps.

Unfortunately it looks like the Twitter event feed is temporarily down (they're blocking it, possibly as part of shutting down the API on Thursday).
