Tchaikovsky is a scammer

Tchaikovsky contacted on MSN (it's trix-xy@ho​tmail.com) telling me that he wanted to purchase my account. He offered to pay $150 for the account plus $5 x amount of pins I can get him. I'm thinking to myself sweet, let's get to it. I told him I wanted to use a mm and he told me you would pay the fees for it. He wanted to use a guy named highkid and I looked it up and found him on sythe and saw that he was trusted so I was fine with that. He then proceeded to invite "highkid" to our conversation and this "highkid" told me Tchaikovsky (name is Joshua on MSN) had already taken care of the fees. Always I was ready to get through with the trade and enough when I saw this on highkid's mm thread:
Always ask for a pm seems I have imposters.
My only msn is [email protected]

I saw that the "highkid" I was talking to on MSN had a completely different address([email protected])and found out that it wasn't the real "highkid". Here is the last few lines of my chat with Tchaikovsky:
