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. This is especially important at checkout as fraudulent credit card testing bots can cause result in chargebacks with Stripe costing you time and money.
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.
