Middleware to block referrer spammers using matomo/referrer-spam-blacklist. It returns a 403 response if the url host in the Referer header is in the blacklist.


ext-intl PHP extension is recommended otherwise symfony/polyfill-intl-idn is used.


This package is installable and autoloadable via Composer as middlewares/referrer-spam.

composer require middlewares/referrer-spam


By default, use matomo/referrer-spam-blacklist as a list of spammers

$spam = new Middlewares\ReferrerSpam();

But you can configure a custom spam list if you don't want to use the default:

$spammers = [

$spam = new Middlewares\ReferrerSpam($spammers);

Optionally, you can provide a Psr\Http\Message\ResponseFactoryInterface as the second argument to create the error responses (403). If it's not defined, Middleware\Utils\Factory will be used to detect it automatically.

$responseFactory = new MyOwnResponseFactory();

$spam = new Middlewares\ReferrerSpam($spammers, $responseFactory);
