The AntiSpoof extension is an extension for preventing confusable usernames from being created. It blocks the creation of accounts with mixed-script, confusing and similar usernames.

For example, if user John Doe is already registered, the extension will block attempts to register:

• joHn dOE ( capital letters in different places)
• Jοhn Doe ( "ο" in Jοhn is Greek small letter omicron)
• John Dоe ( "о" in Dоe is Cyrillic small letter O)
• Јohn Doe ( "Ј" in Јohn is Cyrillic capital letter Je)
• John Đoe ( "Đ" in Đoe is Latin capital letter D with stroke)
• Jóhn Doe ( "ó" in Jóhn is Latin small letter O with acute)
• John ​Doe ( there is a Zero-width space before Doe)
• Jøhn Doe ( "ø" in Jøhn is Scandinavian oe)
• J0hn Doe ( "0" is the number zero)

etc.

Installation

• Download and move the extracted AntiSpoof folder to your extensions/ directory.
  Developers and code contributors should install the extension from Git instead, using:cd extensions/
git clone https://gerrit.wikimedia.org/r/mediawiki/extensions/AntiSpoof
• Only when installing from Git, run Composer to install PHP dependencies, by issuing composer install --no-dev in the extension directory. (See T173141 for potential complications.)Category:Extensions requiring Composer with git
• Add the following code at the bottom of your LocalSettings.php file:

  wfLoadExtension( 'AntiSpoof' );
  

• Run the update script which will automatically create the necessary database tables that this extension needs.
• In case user accounts are stored in a shared database, add:

$wgSharedTables[] = 'spoofuser';

• Run the batchAntiSpoof.php script from the command line to pre-populate the spoofuser table with your wiki's existing usernames.

php maintenance/run.php AntiSpoof:batchAntiSpoof.php

• Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.

{
	"extra": {
		"merge-plugin": {
			"include": [
				"extensions/AntiSpoof/composer.json"
			]
		}
	}
}
