To me, the social media would have been the easiest way to fight against scam, to make beginners get aware "the strangers you meet is at own risk ". This can always be in the mind when one encounter a stranger who want to offer free money or do business, one will have to think how real can it be.
Beginners don't get awareness of scam on social media, some mostly get aware of scam with personal experience.
Social media is possibly the most virtual space we have, because it's not real, thus becoming a favorite place for criminals to run rampant. That social network is the information channel that helps the government and people spread anti-fraud news the fastest.
Today, most national governments, major organizations around the world, as well as local police departments have different social media outlets. New news and announcements are always broadcast on the first social network to help people update the fastest information.
