"Well, wouldn't the real goal for Bing be twofold here?  1) Look faster and more responsive than Google 2) Create a new data source to help refine or confirm algorithmic signals. It's not about how it impacts one (your) site it's the aggregate data that may help Bing to better identify these low-quality sites. It may simply prove to be a confirmation, but it could help refine the identification process. It's essentially a human-curated set of training data." - AJ Kohn
