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:

• 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 place the file(s) in a directory called AntiSpoof in your extensions/ folder.
• Add the following code at the bottom of your LocalSettings.php:

require_once "$IP/extensions/AntiSpoof/AntiSpoof.php";

• 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 extensions/AntiSpoof/maintenance/batchAntiSpoof.php

• Y Done - Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
• To verify that it's working, try creating an account for username "Adm1n"; most wikis have an "Admin" account and so AntiSpoof should reject this lookalike username with a message like "The name Adm1n is too similar to the existing account: Admin".
