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[edit]
- Download and place the file(s) in a directory called
AntiSpoof
in yourextensions/
folder. - Add the following code at the bottom of your LocalSettings.php:
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:
$wgSharedTables[] = 'spoofuser';
- Run the
batchAntiSpoof.php
script from the command line to pre-populate the spoofuser table with your wiki's existing usernames.
php extensions/AntiSpoof/maintenance/batchAntiSpoof.php
Done – Navigate to Special:Version on your wiki to verify that the extension is successfully installed.
To users running MediaWiki 1.24 or earlier:
The instructions above describe the new way of installing this extension using wfLoadExtension()
.
If you need to install this extension on these earlier versions (MediaWiki 1.24 and earlier), instead of wfLoadExtension( 'AntiSpoof' );
, you need to use:
require_once "$IP/extensions/AntiSpoof/AntiSpoof.php";
- 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".
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"
]
}
}
}
