I got some backlinks and it's enough to be first on bing. My site is almost nowhere in Google, only on the third page. I think there is no black hat protection in Bing. They don't care about black hat SEO. More backlinks, better position. Google can ban any suspicious website. However it's useless because nobody using Bing. Maybe 4% of all searches. Only few visitors came to my website from Bing.
