Bing: We Do Not Do One Off Indexing / Ranking Penalties, It’s Not Scalable

Krishna Madhavan, Principal Product Manager at Microsoft Bing, said that Bing does not do one-off search penalties because it is not scalable. Instead, Bing will build a spam algorithm to detect the type of spam it is and unleash it on its index to pick up on not just one site doing that, but as many sites as the algorithm can find. And then it takes action on all those sites, not just one, at scale.
