Any idea what they are doing? If it's just looking for cloaking you think it would be better to not have the search.live.com referrer. That makes it easy to game if you were somehow trying to cloak for the Live bot which I don't think is a real problem anyway.
They say, "Anytime we see a referrer from serach.live.com, we check if the IP is in the range of known IP addresses for their crawler, and if so, we just ignore it."<p>I filter some stats according to user agent name: Anybody know if these bots use regular (honest) agent names? Or do I need to start searching for "range of knw IP addresses for their crawler?" (Anyone care to share such a range?
