Soit via la console Analytics en ajoutant les spammers concernés via Admin -> Informations de suivi -> Liste d’exclusion de sites référents
Cette solution est bien utile pour l’analyse des données mais cela ne fait que rendre invisible un traffic qui arrive tout de même sur votre site

Pour supprimer complètement le trafic, vous pouvez ajouter ceci au fichier .htaccess à la racine de votre site, la liste prend en compte toutes les spammers que j’ai aperçus, vous pouvez bien sur en ajouter à la liste en utilisant la même synthaxe.
