Facebook and Google have banned the placement of binary options on their platform after disclosing information about fraud in this area, in which the loss of UK residents in the six years grew by 400,000%. After that, they began to impose bans on other methods of risky investments, including cryptocurrencies.
Earlier, Bank of England President Mark Carney said that the situation with cryptocurrencies may be similar, therefore, "it is time to regulate elements of the digital ecosystem to combat illegal activities" - and banning advertising is one of the ways of this regulation.
The largest search engine in Russia Yandex also actually banned the advertising of crypto and ICO, but does so on the basis of internal documents. Information about this ban was not officially published.
