What does the Leaky Paywall reCAPTCHA add-on do?
The reCAPTCHA add-on helps prevent automated bots and spam accounts from completing your registration forms.
Your Paywall Project managed Leaky Paywall set up uses invisible reCAPTCHA v3, which means:
- There is no visible “I’m not a robot” checkbox
- No challenges (traffic lights, buses, crosswalks, etc.)
- The system works entirely in the background
Google silently assigns every visitor a score based on how “human” their interaction appears. If the score is too low, Leaky Paywall blocks the registration from being submitted.
We keep it simple: good scores pass, suspicious activity is stopped. 😊

How Leaky Paywall Uses Invisible reCAPTCHA v3
When the registration form loads:
- Google evaluates user behavior (movement patterns, browser signals, IP reputation, etc.).
- A score between 0.0 and 1.0 is returned.
- 1.0 = very likely human
- 0.0 = very likely a bot
- Leaky Paywall checks your chosen threshold (the “Score” setting).
- If the score is below your threshold, the form cannot be submitted.
