bonjour,

il y a quelque temps j'avais trouvé cette liste pour bloquer les aspirateurs de sites via htaccess:

Seulement je viens de m'apercevoir que cela blolque également l'accès a certain de mes outils...comme...
http://www.spider-simulator.com

Pourtant a priori rien de méchant pour ce site ???

Qu'en pensez-vous ?
Je pose surtout cette question pour le référencement, cela ne posera pas de problème au moteur d'indexation ?

Webmaster expérimentés: inserez-vous systématiquement ces codes pour éviter un maximum de pb ?

Merci de votre aide.
