Hi everyone,We're excited to share our first XenForo add-on with the community!
What does it do?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.
Key Features
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
