He's asking for duo ques and basically says "i'll pay you after one game" then keeps stringing you along for as long as he can with promises such as this is a big boost i'll pay you for plat-diamond etc... etc...
And he does this by convincing you that you can trust him by giving these pictures and doing a sob story how the last booster got his main account banned. It happened to me a while ago but apparently he's still been at it since my friend got approached by him.
