Facebook bans cryptos???

Halooooo Steemians, i've been away for a short while but am back now. I just saw these messages of facebook banning crypto currencies ads and its kinder weird for me. i haven't really gone deep into this subject but am here to do that now. Sure it has its good, bad and the ugly sides. In my opinion this ban would help in getting these scammers off in swindling the unsuspecting users. The bad side to me would be that some people can't genuinely promote their ideas about the cryptos and the ugly side to me would be that this can diminish the interest of most users with regard to promoting cryptos on facebook.
