I’m having trouble finding information on what kinds of offers Bing allows and disallows. Facebook makes this pretty simple with their terms, but I can’t find similar documents on Bing.
All that I know from looking around is that they dislike BizOps. I’m not interested in cloaking at this time.
Bing is pretty lenient, but yes, they’re not quite fond of Bizopps. But the one thing that distinguishes them from Adwords is they allow download offers.
Other than that, they accept Adult too.
