I'm sorry for your loss, but man. Please make this a valuable lesson for you to take. At least it wasn't $100 or even more.
Even if he was legit, he would have sold you cracked/hacked accounts that will most probably get you tracked down by police. So do take care around this forum, scammers are common.
