These bans are a result of the social media giants being American companies. The line of nonsense about placing the ban due to all of the scammers using the buzz is absolutely ridiculous. The U.S. Securities and Exchange Commission has decided to apply pressure wherever they can in the interest of suppressing the growth and eventual adoption of cryptocurrencies. With google and subsequently youtube following suit on the ban in June of this year ICOs will definitely take a hit without the power of these platforms to disseminate information. How much is yet to be seen after June comes and goes.
