The AntiSpoof extension prevents registering confusable usernames that are otherwise easily mistaken, or circumvent block patterns, or impersonate existing accounts. It also blocks creating accounts with mixed-script 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';

If you see an error about 'spoofuser' table missing, you can try running from mediawiki root folder
```
php maintenance/run.php update.php
```
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.

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".

When installing from Git, please note that this extension requires Composer.

So, after installation from Git change to the directory containing the extension e.g. "../extensions/AntiSpoof/" and run composer install --no-dev, or when updating: composer update --no-dev.

Alternatively as well as preferably add the line "extensions/AntiSpoof/composer.json" to the composer.local.json file in the root directory of your wiki like e.g.

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