This script obfuscates WordPress user data for defined user roles. Making users anonymous might come handy for development environments or other situations where user data should be obfuscated to follow GDPR privacy and data protection requirements.

Easiest way to execute the script is to run it with WP-CLI:

$ wp eval-file obfuscate-wp-users.php
