Facebook has announced a ban on ads for crypto-currencies on its platform, effective immediately.

The new policy actually bans ads for various kinds of financial products and services which are frequently associated with misleading or deceptive promotional practices, with a particular focus on crypto-currencies, binary options and initial coin offerings (ICOs).  

Facebook is keen to reduce the scope for its users to fall prey to the latest types of scams associated with these products, services and practices.  

Acknowledging that its measures are 'intentionally broad', Facebook has indicated that it may well modify the new policy in due course, to allow genuine and good faith crypto-related businesses to advertise again. 

But for now, all bets are off.
