Recently I’ve discovered that the Prosody module mod_register_web supports hCaptcha now. Previously we’ve used Google’s recaptcha which is obviously not ideal for privacy reasons. hCaptcha is more privacy conscious and rewards site owners for using them. As such, I’ve added hCaptcha to all registration forms!
If you’re interested in implementing hCaptcha as an alternative to Google’s recaptcha, consider using our referral link.
