About 1/3 of our traffic is from crawlers (about 250K last month). Is there a way to block these but allow Google’s crawlers?

Ceci est désormais possible via les paramètres du site : recherchez « crawler », plus précisément `blocked crawler user agents`. Il existe également `allowed crawler user agents` si vous souhaitez être _très_ strict et interdire tout, sauf un crawler spécifique.
