Bing immediately takes measures to "de-identify" the data by removing account information that could identify the person conducting the search (email addresses, phone numbers, mailing addresses, etc.). Reese Solberg, Bing's Privacy Manager, states in the Bing Community Post that, "This is a strong step forward in our journey to protect the privacy of our customers while providing a great set of search tools.".
The new policy will be implemented over the next 12 to 18 months. You can find the full announcement over at Microsoft's "On the Issues" Web site.
