Microsoft’s search engine Bing has reportedly blocked over 5 million cryptocurrency-related ads last year, as a result of a ban the search engine enacted in an attempt to protect its users from fraudsters.

According to Bing’s ad quality review, the company’s bad account takedowns doubled in 2018, with cryptocurrency, weapons, and third-party tech support scams being the main problems it faced. Overall, Bing suspended “nearly 200,000 accounts” last year, and removed 900 million ads from its platform.

As covered, Bing banned cryptocurrency-related ads back in May, in a move it claimed was made to protect users from scammers, as the crypto market being unregulated meant cryptocurrencies “present a possible elevated risk to our users with the potential for bad actors to participate in predatory behaviors, or otherwise scam consumers.”

At the time Melissa Alsoszatai-Petheo, who published the company’s blog post on the move, wrote:

To help protect our users from this risk, we have made the decision to disallow advertising for cryptocurrency, cryptocurrency related products, and un-regulated binary options. Bing Ads will implement this change to our financial product and services policy globally in June, with enforcement rolling out in late June to early July.

The move saw cryptocurrencies join other questionable products and services Microsoft banned from its platform. These include Ponzi and pyramid schemes, and the mentioned third-party tech support scams.

Bing notably banned cryptocurrency-related ads following bans enacted by search giant Google and social media giant Facebook. These two firms have since started allowing crypto-related ads from a few companies.

At the time, various cryptocurrency associations threatened lawsuits against the tech giants over what they claimed to be “cartel collusion” against cryptos, made in an attempt to manipulate the market.

Although Microsoft’s search engine has banned crypto ads, the tech giant itself has been accepting bitcoin payments since 2014. Its website even has a how-to page walking users through the process of topping up their accounts using BTC.
