There's no body that is going to blame the social media for the ignorance and greed of anyone that has fall victim to scammers. The truth is that "nothing is perfect," Like @EarnOnVictor has said. Anything that has advantage also has its disadvantage, the social media have been used to promote so many altcoin project and I am quite sure that through some social media platform, many people have tried to talk their friends into investing in Bitcoin via their chats on those social account.
