Dummy Users Finder & Cleaner helps you keep your WordPress database clean by identifying and removing users with fake or temporary email addresses.
This plugin is essential for sites that have open registration and get hit by spam bots or users creating fake accounts. It intelligently detects dummy emails based on: 
* Known Disposable Domains: A built-in list of common temporary email providers (e.g., mailinator.com, 10minutemail.com). 
* Pattern Detection: Identifies emails like <code>test@...</code>, <code>demo123@...</code>, <code>user001@...</code>. 
* Suspicious Formats: Detects random string usernames and other bot-like patterns. 
* Custom Domains: Add your own list of domains to block/flag.
Key Features: 
* Scan & Detect: One-click scan to find potential dummy users. 
* Domain Analysis: Group users by email domain to find bulk registrations (e.g., 50 users from <code>@suspicious-site.com</code>). 
* Smart Protection: Automatically excludes users who have WooCommerce Orders to prevent accidental data loss. 
* Bulk Actions: Select and delete multiple users at once. 
* Reassign Content: If a dummy user has created posts or comments, you are prompted to reassign that content before deletion. 
* Export: Export a CSV list of deleted users for your records.

Fake User Detector helps WordPress site owners identify and flag suspicious user accounts after they have already registered.
This plugin does not prevent or block registrations. Instead, it analyzes user data post-registration to highlight accounts that appear automated, fake, or low-quality, making it easier to review and remove them manually.
Fake User Detector is designed as a cleanup and review tool, not a registration firewall. It works well alongside other plugins that handle CAPTCHA, email verification, honeypots, or other signup prevention techniques.
Features:
<ul>
<li>Post-Registration Analysis: Evaluates user accounts after creation to identify suspicious patterns.</li>
<li>Gibberish Detection: Flags accounts with non-human patterns like too many uppercase letters, no vowels, or clusters of consonants.</li>
<li>Symbol and Number Filters: Detects unnatural use of digits or special characters in names.</li>
<li>Customizable Detection Rules: Enable or disable individual checks to suit your site’s user base.</li>
<li>Flag for Review: Suspicious accounts are flagged and marked for potential deletion.</li>
<li>Admin Notice: Quickly see how many flagged users exist from your admin area.</li>
<li>Scan Existing Users: Scan the users admin list table for suspicious accounts so you can easily delete them.</li>
<li>Gravity Forms Integration: If using Gravity Forms User Registration, the plugin optionally runs validation checks on registrations submitted via forms.</li>
<li>Developer Hooks: Add or customize detection logic with your own functions.</li>
</ul>
Detection Checks Include:
<ul>
<li>Manually flagged by admin</li>
<li>Excessive uppercase letters (more than 5 in a name unless all caps)</li>
<li>No vowels in names longer than 5 characters</li>
<li>Six or more consecutive consonants in a name</li>
<li>Presence of numbers in names</li>
<li>Presence of special characters other than letters, numbers, and dashes</li>
<li>Similarity between first and last name (exact match or one includes the other)</li>
<li>Very short names (2 characters)</li>
<li>Invalid or disposable email domains</li>
<li>Excessive periods in email address (more than 3)</li>
<li>Username containing URL patterns (<code>http</code>, <code>https</code>, or <code>www</code>)</li>
<li>Known spam words in user bio or name</li>
</ul>
Fake User Detector is ideal for membership sites, communities, forums, or any WordPress site that allows user registration and needs a practical way to review and clean up suspicious accounts that already exist.
