Don't buy accounts and this won't happen.  I'm not saying I'm happy you got scammed, but this is exactly why buying & selling bitcointalk accounts is shady as hell.  

In addition, this jackoff was already tagged by hilariousandco and me, and this isn't the first scam accusation against him.  You would have done well to check his feedback before entering into a non-escrowed deal for an account.  AND his e-mail was changed recently.  Serves you right.  Maybe you need some new glasses.
