This plugin gives site administrators precise control over who can register, comment, or submit forms. It is designed for site owners who need to reduce spam, restrict access to specific user groups, or enforce registration policies.

Domain and Email Controls: Block or allow users based on specific email addresses or entire domains. You can manually create lists or use integrated services like DNSBL and SpamAssassin's free domain list.

IP Address Filtering: Restrict registration attempts from specific IP addresses or ranges using wildcards for flexible blocking or whitelisting.

Integration and Logging: Works with Contact Form 7 and includes a registration log to track all blocked attempts. Supports ChatGPT to analyze registration data for authenticity.

Flexible Rule Application: Use wildcards in lists (e.g., *@domain.com) and manage reserved usernames. The tool can operate in a strict whitelist-only mode or a standard blacklist mode.
