UserCheck - Block Disposable Emails 1.0.1

We're excited to share our first XenForo add-on with the community!

UserCheck blocks users from registering with disposable/temporary email addresses. It uses the UserCheck.com API to validate email addresses in real-time during registration, helping to reduce spam accounts and improve the quality of your member base.

✅ Automatic Detection - Validates against a daily updated database of disposable emails and domains
✅ Two Validation Modes - Choose between full email validation or domain-only (for privacy)
✅ Free Tier Available - 1,000 API validations per month at no cost
✅ Easy Setup - Auto-redirects to settings after installation
✅ Clean Integration - Extends XenForo's existing validation with no core modifications
✅ Fail-Safe Design - If the API is down, registrations continue normally

Why do members want to download UserCheck - Block Disposable Emails from here? Because this resource was immediately available as of 2025-05-26, It received professional maintenance and updates when it was released synchronously on NullPro.

​

How it Works​

1. User attempts to register with an email address
2. The add-on checks the email/domain with the UserCheck API
3. If it's a disposable email, registration is blocked with a friendly error message
4. If the API is unavailable, registration proceeds normally (fail-open design)
5. Download the add-on
6. Upload to your XenForo installation
7. Install via Admin CP
8. Get your free API key from app.usercheck.com
9. Configure and you're done!

• The add-on itself is completely free
• UserCheck API offers 1,000 free requests/month
• Paid plans available for larger forums
• XenForo 2.3.0+
• PHP 7.4+

We'd love to hear your thoughts and experiences with the add-on.
