Bing is a very famous web search engine owned and operated by Microsoft. A couple of days ago Bing reported in its Blog that online fraud involving financial services became a serious problem recently. Bing published a list of policies to help ad providers meet approval and protect consumers and businesses from being victimized. The polices apply to all forms of currency including real and virtual currency.
Advertising for the following products and services is not permitted: Ponzi schemes, pyramid schemes, or other legally questionable business opportunities, particularly if returns on investment rely solely on adding participants to the scheme or the consumer must pay a subscription fee or buy a specific product to join, and the value proposition of doing so is undefined.

Bing now bans ads related to solicitation of funds except by recognized charities or organizations. Advertisements related to virtual currencies designed to facilitate illegal purposes, to avoid applicable taxes, money laundering, promotion of fake/forged virtual currencies are also prohibited. The full ban of such ads is expected in late June or early July.
Previously, we have reported that Facebook created a new policy that prohibits all advertisements for cryptocurrency and ICOs as part of an effort to improve the integrity and security of ads.
