I just don't understand why people scam for 50$. It take months to build a profil on social media. They maybe make 0.1$/hour. They could make so much more 
I don't know if anyone else has heard it, but I heard this awesome thing you can do known as "account purchase" , apparently you can sell any of your old social media accounts in bulk for pennies. /sEither that or he just scammed you because he could. There's been scams done here for less than a dollar, can't ever be safe without using an escrow.
