• Facebook is banning all ads related to cryptocurrencies, from ICOs to bitcoin.
  • The social network says the ban, which includes both Facebook and Instagram, is to crack down on scams.
  • Cryptocurrencies are "frequently associated with misleading or deceptive practices," it said.

Cryptocurrencies are a Wild West of sorts -- and Facebook has had enough.

The new rule "prohibits financial products and services that are frequently associated with misleading or deceptive promotional practices, such as binary options, initial coin offerings and cryptocurrency." 

It's a far-reaching policy, and Facebook describes it as "intentionally broad." 

(For the uninitiated, initial coin offerings, or ICOs, are a largely unregulated method for company fundraising that involves selling investors cryptographic assets, in a similar vein to an IPO.)

A Facebook spokesperson told Business Insider that the new rule bans all ads related to cryptocurrencies -- not just those directly trying to sell cryptocurrencies or cryptographic tokens. So ads for Bitcoin wallets are also banned, for example, as are ones for Ethereum-mining hardware.

In a blog post announcing the news, Facebook product management director Rob Leathern suggested Facebook may tweak the policy at some point in the future to let legitimate crypto-related businesses advertise again.

"We want people to continue to discover and learn about new products and services through Facebook ads without fear of scams or deception," he wrote. "That said, there are many companies who are advertising binary options, ICOs and cryptocurrencies that are not currently operating in good faith."

"This policy is intentionally broad while we work to better detect deceptive and misleading advertising practices, and enforcement will begin to ramp up across our platforms including Facebook, Audience Network and Instagram. We will revisit this policy and how we enforce it as our signals improve."
